Realized I didn't answer your question about cleaning: you are definitely right, the fully hardened liner is hard to scrub down and eats towels. Our plan is really to not clean itWe'll be on the road for over a year, frequently on dirt, and I doubt we'll even attempt to wash it more than 5 or 6 times
It may be worth taking some temp readings inside along with ambient weather data before you paint the fiberglass to see in hard numbers just how much the color changes the temp inside the vehicle. Food for thought anyways.
Did you get the complete kit and use the shutz gun that came with it or did you buy a better one?
Did you prime the whole thing before you sprayed raptor liner or just bare metal spots? Did you exclusivley use upols acid etch primer?
Thanks
