Can an auto paint shop do a decent job of acrylic clearcoat?
Once plasticoat is exposed to UV for a few days, the aging process starts. If the trailer is kept undercover, it might last another year, beyond normal. This is an average age.
Auto paint shops normally deal with steel and plastic parts to paint.
Painting aluminum properly, is very different, especially on an Airstream.
First, all the old plasticoat must be removed.
No acid is to be used. Sanding, not scuffing, but sanding with 120 to 150 girt sandpaper is a must.
Then 2 coats of epoxy primer should be applied.
Let the primer out gas for 3 or 4 days.
Now you have a substrate that has bonded properly.
You can now apply whatever color paint you want with at least two double wet coats. High quality paints should be the only choice.
Then, immediately, two double wet coats of clear should be applied.
That will give you a paint job that will last 20 years or more, as long as you wax it once a year.
