Glassing
After “stitching” together both sides of our RV’s damaged rear cap, the next step was to apply layers of fiberglass until the “valley” between each side was filled.
Very tedious process.
First, the tools of the trade . . .
I went the “polyester” route instead of using epoxy mainly because of the YouTube video series I watched – Boatworks Today . . . https://www.youtube.com/@boatworkstoday
Because I used polyester resin, I could keep adding layers of fiberglass with “laminating” polyester resin without needing to sand between each layer. However, the last layer needed to be sealed with either a “finishing” polyester resin or Gelcoat with wax. I used the Gelcoat.
Glassing
Laying down all the fiberglass layers took a few days. At most, I could apply two layers a day.
Sanding
The fiberglass layers ended up with plenty of bumps and rough edges so sanding was necessary to flatten the surface . . .

This puts me in mind of boat work I used to do. We would apply the 50 yard rule, “ if it looks good at 50 yds”. I admire your diy handiness.
