Randy from Manitoba needed to re-do his RV's roof. Fiberglass RV Roof. The roof has seen better days. First he added a layer of plywood to the existing roof and then fiberglassed over top of it to make it waterproof. Here is a list of materials he purchased:

  1. Pro Glas 1100/1200/1300 Epoxy Resin- Part A - Gallon (#100120110)
  2. Pro Glas 2:1 Epoxy Hardener- Part B (2:1 mix ratio) - Medium, 1/2 Gallon (#100220509)
  3. 6 Ounce Fiberglass Tape (50 yard rolls) – 4" (#154R4)
  4. Deluxe Rollers- Aluminum - 3/4" x 6" (#674756A)
  5. 4 Inch Spreader - 6" (#657G)
  6. 4 oz. Fiberglass Fabric- Type #1522 (50 inch width) (#1523750)

Since Randy's main goal was to waterproof the roof, he went with the Pro Glas 1200. Fiberglass RV Roof.  Epoxy is the best resin for waterproofing.  The UV protection in the resin will also retard the yellowing of the resin.  Here are a few photos of him laying down the plywood and the finished roof.

    One of my exterior fiberglass panels on my Travel trailer got caught on a tree limb. It broke a 4.4 foot by 10 foot section of the fiberglass off. Can I use mat and resin to replace the section of panel with and if I can will you email me the list and cost please.

    REPLY from fgwarehouse: How thick is the fiberglass panel? If it is .025″, then you want 3/4 oz. If it is .05″, then it is 1.5 oz material. You will need 5 yards x 50″ to cover the area. And a gallon of GP laminating resin. Are you planning on gel coating it?
