I have a few places inside the hatches of my 2012 Margay where the fiberglass on the inside corners is paper thin, and have already started to cave-in. I was thinking of using some 3M 5200 to fill in those spots so they dont keep crumbling. The spot where the latch of the hatch is closed is also cracking and being broken away on many of the hatches.Any suggestions on how to keep the fiberglass corners from caving in and the fiberglass eroding at the latch bar contact-points would be greatly appreciated.Thanks,CraigLast edited by cjrich on September 13th, 2014, 11:15 pm, edited 4 times in total.
