My thoughts exactly!
First he is not going to reinvent the wheel, pissing around with crap we got rid of 50 years ago and who wants to be redoing a job over, I have @800 hours on this vette and 40 more to go on the Air conditioning, about the first time I have a paint problem anywhere, it would probably turn into a Hagerty Insurance Fire sale at this point.

I will never understand, unless he does not paint and just wants to see his name in print or the aggravation he can rile up, going by his other posts.

I never said I was going to paint anything with it... just trying to see if what you said was not BS... but don't get mad, I do that just out of curiosity...

Nitro lacquer is a thermo plastic - it drys by solvent evaporation. Urethanes use a catalyst to kick it over, this is a chemical reaction that does not need air.. It will dry even in the can once catalyst is added. Once cured, they can not be reversed. A thermo plastic can be some what reversed in that when heat is added, it tries to go back to a liquid i.e. easy to burn with a buffer. Adding hardner to a thermo plastic will do nothing for durability, may not work at all and could be far worse than lacquer by it self. Best results with nitro lacquer is to get a product like PPG makes which is modified with Acrylic resin to add durability, but still not as good as a catalyzed Acrylic Urethane system or even the new waterborne systems.

Sounds like a recipe for disaster! .... and I hate having to not only repaint, but having to strip it completely, then prep it all over again, then pay for another round of materials. Why risk it when you can buy a proven product???

......unless you like pain and suffering. :-o

He's just here to rattle people's chains. He said that he never said he was going to spray these frankenstein concoctions he likes making. Just throwing money down the drain. He thinks he's a backyard "chemist" and going to make some kind of discovery. He plays with 50 year old technology trying to make it better, when the manufacturers made it better 47 years ago. He's one of those guys that no matter how much proof you have for or against something, he's going to still do it to see if you are lying to him. The cheapest urethane they make now is better that whatever he is concocting. The best thing to do is to ignore his threads and posts. Legit questions are one thing, but telling BarryK that he was just seeing if what BarryK told him was bs just proves his intentions.
