Hmmm. Collector....do our vans qualify as collectors? I do get it out,,,,sage brush pin striping etc... I think single stage Urethane may be way to go....better long term...if paint is thick enough should be able to get pin stripes out....keep it looking good for years to come......
Relative merits of single stage versus Basecoat clear coat...I think (my opinion) single stage may be better option....don't necessarily think base coat/clearcoat is being done today because it is better....there are many things that drove industry that way...$$$. course only my opinion...
I do have a penthouse pop top...which complicates paint job...a little...I am changing colors so...doorjams...etc...When they did your van id they remove rubber...handles mirrors..etc...or just tape around it?
