Unfortunately UV rays and heat from the sun slowly destroy other plastic items on an RV's roof like vent covers, bathroom shower skylights, refrigerator vent covers, antenna mount sealants and cabling, sewer stacks, air conditioner mount sealants, etc..
How do you repair and replace the above types of items and/or their seals if they're held in place around their edges with this super roof sealing acrylic based material? It sounds very difficult to do, while afterwards still maintaining the integrity of the original acrylic coating job.
