Thread: Fiberglass Boat Repair

Got some reasonable Garks well into the glass that need repairing (from original trailer set up ). So Im off to get repair stuff . Its all below water line , its white gell coat thats more cream now . Some on the chines so it can't be to runny as it needs to hold a shape or over fill and sand ?. Not too worried about the colour more about strength and watertight really . There heaps of product all saying they will do the same repair .Im sure that some are better/easier than others Any help be appreciated . Cheers munsey

Munsey I am repairing mine at the moment also. It had a crack which turned out to be 1m long once I opened it up, I thought it was 3 separate cracks looking through the gelcoat. I opened it with a angle grinder if one of those flap sander things.
And after letting everything dry out have started to re-glass, doing it from underneath is a bitch. I bought my first lot of product from Mitre10 using Polyster Resin products rather than Expoy. But have found a place called https://www.fibreglassshop.co.nz/ and will buy my next lot from there as I have a new floor to put in and also some beams to replace and glass in. My floor was rotten as all hell.

Depends if it's structural or cosmetic, you can guess which one the arse!

Go with Puku

Back in my boat building days , for any cosmetic chips or etc I used to use white gel coat with with a pigment to match the existing colour and mixed with white micro balloons to thicken to a user friendly paste then add MEK a good tip is to use 2 inch clear tape after you have filled to cut down on sanding -wet . Go through the grits and you will be sorted.

I will confess, I have learnt a lot while undertaking this ah project. But it has taken a while since I started it before winter and it was too cold to set. And also to go over to the workshop at night. But I'm to cheap to pay someone

I used to make large climbing holds with fiberglass and can certainly vouch if you are doing large areas then go to a fiberglassers shop or online to get a far better deal.
Used to get 4 litres of resin at a time and either chop, mat or sail cloth for filling plus some colouring for a pretty good price.

Humidity is a prick on the curing times if you haven't found that out already.
Sounds like a fun project.
