If it does, this would greatly limit the paint strippers you could use without effecting/damaging the clear coat.
That being said, if it doesn't, Klean Strip Aircraft Stripper should work just fine. If your trailer does
have clear coat, this product will also remove it...which you would not
want to do unless you were planning on removing it from everywhere....a major job!
Another stripper that works well is Bix. Bix can be found at a Home Depot type store, the Aircraft Stripper at Auto Zone, Checker Auto Parts, etc.
Good luck with whatever you decide to try...always wear gloves & follow all label instructions.
P.S. We have a page on our website specifically addressing our findings on different strippers in the "During"
