1995 1207KB Cracks at the corners repair

[D&JHayes]

We just purchased a new to us 1207KB and as I have started to prepare it for an overhaul and update I noticed several cracks in the corners of the plastic or fiberglass that cover the front and rear of the camper.

Any idea what this material is and a solution to the cracking? They run from the top straight down for about 2 inches.

Any help would be greatly appreciated!

When my 1995 Jayco camper started to crack.....I treated the cracks like I would on Air Craft sheet metal.....I took a small drill...1/16 of a inch...and drilled a hole at the end of the crack...Do each crack this way.....The hole needs to be at the end of the crack....as so the crack ends in a radius....This should stop the crack.....Them I filled the crack and hole with GE silicone calk...This worked for me.....
