Urethane Clear Coat

Don’t use it
It will yellow on ya

 

Some 2 part clear coats will melt your paint job away. Always test on the backside before proceeding on the show side.

 

I use the following with no issues whatsoever. 4:1 and purchased on Ebay. Just make sure you wear a respirator and spray booth. It can crystalize your lungs.

My boss uses it, yes he wears a respirator. Even with a separate paint room, I try to avoid the whole shop when he sprays. That is some harsh stuff.

If you want to use a two part urethane like Cecil suggested, try your local auto supply. That's where we get ours.

 

Believe it or not I can't get it at my local Nappa or Auto zone.
