I wanna be Dave
I’ve sprayed several lexan bodies on the exterior using Krylon Fusion and similar. They’ve held up extremely well. Having said that, it’s all in the prep. You’ll want to scuff the whole exterior with a scotchbrite pad. Wash with Dawn dish soap (Dawn specifically works best for me). Allow it to dry. Then, just prior to paint I wipe down the whole body again with isopropyl alcohol. From this point on, I only handle it with latex gloves to avoid oil transfer. Use the same technique you would spraying inside the body, i.e., lots of light coats. I just did the JK Jeep body for the rig I did for my brother this same way. It got absolutely thrashed on this week as he learned to drive. Other than the usual scuffs, it held up great. Same thing with my blue Comanche body. I also heat cycle the paint between coats using a hair dryer. (From both the inside and outside).
