r/fiberglass

The part here is made out of ABS, its the mudguard from a triumph.
I tried making the mould out of this part, applied gelcoat for the first layer, then iso polyester resin and the gp resin, the iso and gp where applied on chopped fiberglass.

I also applied a lot of pva release agent (the blue visible in the mould), how do i avoid this in the future

Looking for any advice on this project. I have two boat consoles that are fibreglass with a plastic layer of some sort. The outer layer is cracked in many places and I need to repair. I am thinking of filling the cracks with epoxy resin, then putting a layer of cloth and epoxy resin on the entire piece. Then finish with more epoxy and sand, and then paint. If anyone has any tips that would be great.

Hi everyone! The other day I went to reinstall the speaker system in my motorcycle fairing and discovered a huge crack near where the fairing mounts to the bike. The fairing was a custom fiberglass unit from a company not around anymore, so it's hard to get info. I am a complete novice to fiberglass repair, but I've been doing lots of reading up and plan on trying to fix it. My main confusion is the texture I found when inspecting the fairing. It has many little bubbles and a texture almost reminiscent of popcorn ceilings, just with smaller peaks. I included a picture of the outer portion of the fairing, where the fiberglass matrix is clear and visible. Am I seeing some sort of gelcoat? The plan right now was to order some fiberglass cloth and 5:1 epoxy from Totalboat, grind it out down around the very long crack and apply a generous support from the back. Any advice or info on what material i am looking at would be greatly appreciated. Thank you!!

Pretty much have to redo stringers, deck, paint, gel coat, steering cables, electronics, and trailer.
Any suggestions on how to get epoxy and glass that won’t break the bank?

Weird question, but I have a prop that I need to cure at 200 F. It needs to be wrapped around this fiberglass mannequin. Not sure what else it's made of, but it's hollow and clearly has fiberglass as part of the shell. Can anyone tell me what this is and if it's safe to heat to 200F/will cause toxic off-gassing in my oven/is a Darwin Award candidate?

Found this in the middle of fire pit after burning last night and it didn’t seem to burn, I’m a little worried about playing with it and wondering if it’s asbestosis or not.
