Auto clear coat, can i put a coat of urethane over a thin coat of lacquer?

my truck was repainted by someone and there is only a very thin coat of lacquer clearcoat on it and its not very glossy at all. im trying to get a deeper look to it and a shine, i was wondering if i could shoot couple coats of urethane over the thin coat of lacquer clearcoat that has already been on it since last summer. it doesnt have to look perfect, just better, and it doesnt have to last forever, just a few more yrs maybe . any advice would be great, thanks :) hope everyone is haveing a good weekend!Auto clear coat, can i put a coat of urethane over a thin coat of lacquer?
It isn't recommended by most paint companies, but it might work. Test a small spot to make sure it doesn't soften the lacquer and cause lifting. Make sure to sand the old finish dull with a gray scotchbrite pad. I wouldn't expect more than a couple of years durability, and less if it is a dark color %26amp; gets a lot of sunlight.Auto clear coat, can i put a coat of urethane over a thin coat of lacquer?
have you tried to buff it out if not get 1000,1500, and 3000 grit sand paper a bowl of water good size bowl put dish soap like dawn in the water start with the 1000 and work your way up to the 3000 go over the car at least once with each grit when you are sanding make sure you keep the paper wet if you look at the paint while you are sanding you will see the difference from sanded and unsanded when you are done the paint will look like it has a smooth dull coat you are now ready to buff start slow until you get the hang of it don't go to fast you will burn the paint and don't stay in one spot to long same with sanding you will need a high speed buffer this will make your paint look deeper and like glass or you can wet sand the hole car tape it up and put your clear coat over what you have there you may still have to buff it out oh yah you will need buffing compound and polish
your better off totally repainting the car,,,the basecoat is easy to apply and the clearcoat is not cheap,,,so why go half way

Do I need to / can I spray a clear coat on top of a Rustoleum spray lacquer?

I have fully prepped and painted a plastic piece with Rustoleum high gloss black lacquer from an aerosol can. The finish has come out almost mirror like after a few sanding cycles.





I'd like it to stay this way. I'm not familiar with lacquers (or whatever came out of this can). Can I buff / polish the lacquer directly or can I apply some sort of clear coat on top?





Thanks.Do I need to / can I spray a clear coat on top of a Rustoleum spray lacquer?

  • Which is more durable outside, lacquer (such as Garco Sealer) or polyurethane (such as Minwax Clear Shield)?

    assuming that yellowing from the sun is no factor at all; only resistance to cracking, peeling, chalking, etc. for protecting the wood surfaceWhich is more durable outside, lacquer (such as Garco Sealer) or polyurethane (such as Minwax Clear Shield)?
    Do not use polyurethane. It isn't meant for use outside where it's exposed to UV. It will deteriorate and worse the color of the wood under it will deteriorate. Spar varnish is best. It gives a good clear, non yellowing, non deteriorating coating for out side surfaces. It's the best coating for a wood door or the like. I did my solid wood, west facing, Kitchen door with spar varnish in '86 and it still looks great today. You can purchase Spar Varnish at any paint store, home center or hardware store.





    EDITED: I tried Marine Spar Polyurethane on my front door three years ago. It's in terrible shape and Im preparing to take it down and redo it. Spar Varnish is far superior.Which is more durable outside, lacquer (such as Garco Sealer) or polyurethane (such as Minwax Clear Shield)?
    You can use products like Minwax Clear Shield or Minwax Helmsman Spar Urethane. These products are good for exterior use and will be resistant to sun, moisture, etc. You will however have to repeat the process every 2 or 3 years based on what type of conditions the surface will be exposed to. Clear Shield and Helmsman are actually the same product as I recently found out from a Minwax rep. I have experience selling both products in my store. I do not have any experience or knowledge of an exterior lacquer clear coat.
    Look for a ';MARINE SPAR POLYURETHANE';

    Should I spray coat my mountain bike with clear automotive lacquer? Plus another question. Thanks!?

    I have a very nice Cannondale mountain bike that I bought about 9 years ago. It cost about $1700.00 back then and I have not ridden it much at all. The paint is still in perfect condition and the only signs of wear are a couple nicks in the rubber on the handlebars from having it turned upside down on asphault. I have been thinking about selling it since I hardly use it and I would like it to be in the best condition possible. Do you think it would be a good idea to spray cover it in a coat of clear automotive lacquer give the paint some extra strength and to prevent the paint from chipping?





    I know Cannondale uses that stuff to spray cover the entire painted parts of the bike during the manufacturing process but does that stuff break down/wear off over time?





    One more thing... how much do you think I could sell it for? It's a Cannondale Jeckel with front and rear lockouts for the full suspension. I bought it in 2000 but like I said, it has rarely been ridden and looks practically new.





    Thanks so much!Should I spray coat my mountain bike with clear automotive lacquer? Plus another question. Thanks!?
    Do not spray the frame with anything! No need to as long as the clear coat is still present on the paint from the factory which I believe it is. Since you barely used the bike and the handlebars can easily be replaced then LEAVE IT ALONE. Any clearcoat will probably not adhere properly to the existing clear coat and you would need to strip the parts off to respray it anyway. Sell it as is and you will get more money for it as is!Should I spray coat my mountain bike with clear automotive lacquer? Plus another question. Thanks!?
    WAIT a minute.


    What automotive clear coat lacquer??





    Modern base coat/clear coat automotive finishes now days are not lacquer at all. Some are now water borne -- even aftermarket. Most cars are sprayed at the factory with water borne.





    The point: These systems have to be compatible with one another, the paint on your bike is not compatible with today's auto finishes.





    It would take a total strip and refinish. Leave it alone.
    Spaying your bike with a clear coat will probably screw it up and reduce the value. Sell it like it is.

    How to remove runs from car paint clear coat / lacquer? Run razor or wet sand?

    Hi there,


    today I painted and clear-coated my car's wheel arch after what seems like forever prepping and filling to remove rust.





    However I was too enthusiastic with spraying the clear coat and I have a couple of runs in it.





    What's the best way to remove the runs? I've heard of ';run razors';, but I don't know if the clear coat will have hardened too much to shave off by next weekend. How long do you have after spraying clear before it's too hard to shave?





    I've also read that wet-sanding is the way to go, but I'm concerned that this will ruin the finish? Is it possible to restore the shine after wet-sanding clear coat?





    Many thanks!How to remove runs from car paint clear coat / lacquer? Run razor or wet sand?
    You are best using wet and dry papers, use one medium grade to take it down to level, a less abrasive one to remove abrasion marks then a very fine to finish. Follow this by buffing with a polishing compound followed by wax a shine.How to remove runs from car paint clear coat / lacquer? Run razor or wet sand?
    it's very simple, and honestly you should do this after painting whole cars too, after you put the clear coat on you wet sand it. It helps drastically.
    wet sand it and then wax it

    I coated wood with clear spray lacquer and now it looks odd?

    The lacquer looks okay... but while I was spraying it the lacquer had what looked like tiny stringy pieces of glue or dust... or little fuzzies. I don't know how to describe it. I put about 3 coats on. Did I do something wrong? Will these little stringy dust looking things dissolve while it dries? If not, how do it get rid of them?I coated wood with clear spray lacquer and now it looks odd?
    Generally you sand or rub between coats of anything. Get some really fine steel wool and give the project a good rub - blow it off and spray on another light coat. Pile it up - it will look factory after a while.





    You can rub also with just a cloth or fine steel wool dipped in paint thinner. But make sure you throw your cloth outside - don't leave it somewhere to burn your house down!I coated wood with clear spray lacquer and now it looks odd?
    You can do a light sanding with a find grit sandpaper. Then make sure the nozzle of your spray lacquer is clean and spray a light finish coat on it. Lacquer is a trick thing you have to make sure you dry it completely before each coat.

    Can i spray lacquer clear coat over urethane base coat?

    i sprayed my whole car with acrylic urethane single stage and i wana clear coat it too give it that extra shine is it possible to thisCan i spray lacquer clear coat over urethane base coat?
    No, you don't want lacquer over urethane. It's a different material and will very likely peel in a few years or less.





    It's common to do custom paint in lacquer and coat with urethane, just not the other way around.





    You didn't say if the urethane is clear. If it's not, shoot it with another coat of clear urethane. You can then buff it to a glassy finish.Can i spray lacquer clear coat over urethane base coat?
    Unless you've done this before with good results, there are so many different blends of paints and solvents that the only true method of knowing what is compatible with what is to spray a test panel and try it.
