It's warm and overcast outside today, so I figured it was a good time to wash the pup and put on a coat of wax. As I was standing on the ladder and wiping a section, I noticed fine, hairline cracks. As I looked down the side of the pup's roof, I found a few more. All were in a section, close to the edge of the roof track. I can catch my fingernail on them, so they are indeed breaks in the surface, and not just light scratches. I suspect they just happened, because I heard a slight crinkling (for lack of a better description) sound while wiping the wax, and I never noticed them before. Before I get all worked up over nothing I wanted to inquire on the Portal. 1) Are these cracks in the fiberglass normal/superficial? Perhaps just a crack in the outer coating? Can I just put some sort of seal over them and call it good? FWIW, I just picked up a tube of RV Goop yesterday. 2) Our pup has always been garage kept. The roof is/was in excellent condition and there is no AC. The tracks have never been used either. 3) No one has walked on the pup roof, and while I put a little elbow grease into rubbing some spots, I'm not a large person! Thoughts?
