Bondo Fiberglass Resin Repair Kit, 00420, 0.45 Pint

Bondo Fiberglass Resin Repair Kit, 00420, 0.45 Pint

Q: Would this "polyester"-based resin be okay to repair fiberglass on fulcrum of a diving board or would I be better off spending 10x more on "epoxy"?

The real answer would be what you want to accomplish. Structure repair, or cosmetic? I personally would use resin designed for maritime use. Check the data sheet for the 422 to be sure it has some elasticity. Additionally, 422 is primarily for automotive designed to get its UV protection via paint or an opaque gelcoat. This stuff is great and I use it but if not protected it turns yellow and brittle. My "go to" composite repair for composite structural repairs is carbon fiber and epoxy.

Q: does this work on a longboard

It does work on a longboard, but you need more product than this supplies. Not enough fabric depending on the area to repair....only 2" square. You may need more. It does work great....repaired our longboard with fiberglass repair kit years ago.

Q: I have a 1-ton van with a fiberglass roof. It has 3 minor leaks. Can I roll this on to seal the leaks? These are not cracks.

I would say yes. You would just sand the area to rough up the spot and mix the resin according to the directions. Apply a small piece of the fiberglass material on the spot and the put the resin down to where the material is covered. Let dry in a warm area for 24 hours and it should be good. You can then sand the area and paint it. Good luck..
