Rustoleum/Valspar Question

[Sharps40]

I'm reading thru both the body section on rustoleum roll on's and sprayed on and doin some readin on line on the Tractor Supply Store Valspar paints sprayed on.

I think I got it on reducers/hardener and thinner for these less expensive enamels.

What I'm lookin for is some pics and opinions from anyone that:

1. Sprayed on either enamel (not interested in a roll on/sand/buff) - how did it lay and shine and was it as hard enough or even as hard as auto paint?

2. How did the shine, adhesion and scratch resistance hold up over 1, 2 and up to 5 years?

3. Has anyone used the new electric Wagoner 590 turbo HVLP to shoot their vehicle with these paints? Love it or hate it?
