Another travel trailer painting thread, I guess I should make a separate painting web page and have it saved.
To answer: Yes it can be done.
This thread has discussion, pictures, and suggestions about materials used.
Cliff's notes about the how and what: Sprayed on with Graco airless, a primer coat with S-W Industrial DTM primer. Finish coat with S-W Acrylic Super Paint and Rustoleum spray cans for accent stripes. Resulting paint job is now four years old and appears like the day it was finished. Background--I do some painting for a living, mostly residential and commercial facilities. I've done some auto body work on different vehicles and have painted everything except aircraft.
If I had one suggestion to give it would be this: Put 95% of the work into surface preparation. If you can't or won't do that, either hire it out or suffer the consequences.
Imron or any other aircraft/yacht painting systems is unwarranted and will break most budgets. Nobody that has ever suggested to use these paints has used them and their primers. Imron primer will sicken/kill most folks since you need special personal protection devices. I have used these paint systems.
