Tony Enamel Posted June 14, 2006 Report Share Posted June 14, 2006 Hey all. I just painted my latest creation (automotive spray paint) and the clear coats won't stick to the paint. It goes on seemingly beautiful but even the slightest knick or bump and the lacquer comes away from the paint. BTW, I'm using a Varathane gloss lacquer. So, I'm wondering. Do I need to sand the paint coat before spraying the clear? If so, What grit? Am I using the wrong product? HELP!!!!! Quote Link to comment Share on other sites More sharing options...
Drak Posted June 14, 2006 Report Share Posted June 14, 2006 Quite probably your paint and clearcoat products are non-compatable. Sanding the paint might achieve a mechanical bond, but you shouldn't have to rely on that for good adhesion. Best bet is to stay with the same manufacturer for color and clear coat products.

Maiden69 Posted June 15, 2006 Report Share Posted June 15, 2006 Varathane suck with most other paints. It peels like snake skin and once it finish peal;ing nad you want to refinish you ar egoing to have to clean up with naphta or something similar and spray one more color coat. I could recomend the varathane if you were to finish directly on wood. Over paint I don't like it. Quote Link to comment Share on other sites More sharing options...
Tony Enamel Posted June 15, 2006 Author Report Share Posted June 15, 2006 Thanks Guys, So, most likely I'm using the wrong lacquer. I used duplicolor auto paint so I guess I'll try to find a duplicolor clear coat. One more question, Does it matter if my paint has a gloss to it? I heard that you should use only a matt paint and that the clear will give the shine. But The color I want has a gloss to it. Is this OK? Thanks again.

jer7440 Posted June 16, 2006 Report Share Posted June 16, 2006 I would do some research here about the duplicolor clear. I seems to me I have read several bad reports about it. IIRC it takes forever to cure and even after you wait forever the finish isn't very hard. Quote Link to comment Share on other sites More sharing options...

custom22 Posted June 23, 2006 Report Share Posted June 23, 2006 You can use nitro laquer like from stewmac and its usually compatible. Just test it on scrap and make sure the duplicolor has cured. Quote Link to comment Share on other sites More sharing options...
MoCaster Posted June 24, 2006 Report Share Posted June 24, 2006 (edited) Varathane is not lacquer, it's a urethane enamel which you should never use over lacquer. Edited June 24, 2006 by MoCaster Quote Link to comment Share on other sites More sharing options...
Devon Headen Posted June 25, 2006 Report Share Posted June 25, 2006 I've heard a few people say that Deft lacquer spray cans are compatible with dupli color coats. Deft is the best spray can lacquer I've ever used so it gets my vote. Quote Link to comment Share on other sites More sharing options...
guitarchump Posted June 26, 2006 Report Share Posted June 26, 2006 Minwax poly anyone? My friend finnished his guitar with auto paints then used Minwax poly as the clear coat and it worked fine. try it on a scrap. It cures fast which is good and bad. You must never take more then a day break when adding coats or you could get witness lines. But other then that i love it for a finnish thats from a can.

Tony Enamel Posted June 27, 2006 Author Report Share Posted June 27, 2006 Thanks for all the feedback, guys. I'm in Canada (ontario) and can't order StewMac nitro. Does anyone know where I can order nitro from that will ship to me? Quote Link to comment Share on other sites More sharing options...
AlGeeEater Posted June 27, 2006 Report Share Posted June 27, 2006 (edited) To me Dupli-Color never cured, and even if it did cure it was very, very soft just like it had never cured. Don't get me wrong, it's a GREAT finish for beginners, it sands easily, buffs out easily and looks good buffed but it's not a brand you'd want to paint 20 or 30 guitars with and sell them. Love my spray rig. I'm not sure about products in Canada, but you might want to check 'Canadian Tire' or something like that for spray cans.
