Maybe I try to discourage some from trying to make half a donkey out of their project and at the same time get them to start thinking about something closer to Original or at least more 'professional'... The 'slap some paint on it' just seems so.... 80's.
I use the Yota example only cause the 56 GMC bed on an 88 Toy IS
Original...

so right there "Original" is what 'I' say it is.
In this case a Black Epoxy primer is the original paint.
My 58 GMC 1/2 ton on the other hand...
