I hope we don't spray it down with it
The paint that is in there now is pretty rough, between fuel spills, brake fluid drips, scratches, and some bare metal where I was doing some fabrication.
I was going to just scuff it with paper then hit it with scotch bright. Then spray it with a good self etching primer or epoxy primer re sand then paint. I like the idea of the single stage urethane, I don't want to get into spraying clear if I don't have to. I'm just a garage hack trying something new.
I THINK the original paint was lacquer, and then dad hit it with a spray can after some scratches and spill from taking the motor in and out.

Does this sound right?

Thanks again guys for all of your advice and help.
