Cleaned my door panels yesterday. Spray painted the plastic top parts and the latch release cups. Didn't see this hairline crack till after I sprayed it. Roughed it up with sand cloth and epoxied it. Used a piece of sandcloth as a backer. Forced some through the crack and wiped excess off front. When dry, painted with a couple coats of Krylon Dual. The foam that sorta seals around the handles was shot, so I replaced that. Put new plastic barrier on the doors.
