They musta used diluted xylene (uhhh... on the coach, not on the tires, I mean
). I tried xylene on a very inconspicious spot on the coach and washed it off right afterwards - still discolored the paint a little.
I think getting that film off is kinda like waiting for Christmas, it's going to happen but on its own schedule and you can't really hurry it. I bet the UPS guy thinks I'm starting a meth-lab or something with all the various 'HAZARDOUS' label chemicals he's been delivering of late. I've tried 'em all.
A heat-gun and plastic blades works very well, but there's an extremely thin-line between enough heat to soften the film and too much heat and softening the paint too
. It was too tough to keep that distance & heat & time regulated without causing damage. Don't have to ask how I know.
Having the best luck with a Wagner wallpaper steamer and orange plastic razor blades. I took off the attachment on the end, and use just the hose nozzle pointed close to the film for maybe 5 seconds. Once it starts, it's easy to just move the nozzle slowly and follow it with the blade. Takes a lot of blades tho, they bend and then break easy with the heat.
I follow it with 'Rapid-Remover' or with 'Quick-n-Easy', and more blades. QnE seems to work a little better, but will fog the headlite plastic when/if you get some on it (and now I have another job to do
).
I'd say we have maybe a total of 12 hours into it so far and are about 3/4 done, so I guessing 16-18 hours total to complete. And that's not all at once, more like an hour here and 20 minutes there, etc. That's also not counting the attempts with different methods or materials, because I'd only do maybe 1/4 square foot each time, down low where it wasn't seen easily if something went wrong.
I hope this helps. It's not a fun-job but not difficult either, just time-consuming. But WOW! does it look better afterwards!!!
