Fibreglass/ repair advice please
Hi all
was doing a bit of a hull inspection and found this damage (see pic)
Am guessing it was from the nasty gnaraloo track a while back and I never noticed it as it was probably sitting on the roller itself. I ratchet strap the boat down/ let down tyres/ take it easy etc but it still obviously bounced around a bit and hence the damage... or thats what Im guessing anway as other than those trips, the boat only takes 3km sealed roads to the boat harbour and back...
It looks as if its just the gelcoat etc thats missing, as its obviously rubbed down to the glass, and from what I can see it theres no indent/ signs of wear on the acutal fibreglasss itself.
I asked for some advice from the local boat shop up here and hes put me onto a product called Flokote, that apparently mixes with a catylist and just paints on (once the areas been sanded/ prepared etc)... It hardens to a white colour apparently and is a tough resin so hopefully this should sort it out?
Couple of quick questions for those who have expereince in this sort of thing:
- is this the best way to go about repairs/ best product to use?
- Ive been told to just sand back the gelcoat about 10mm around the area (as the flokote wont stick to paint etc), mix it with the catalyst in 1:100 ratio, stir it till it starts to thicken then paint it on, wait for it to dry and then repeat. Any tips/ advice on the process?
- Rollers: The local boat man also mentioned that the rollers on the trailer might be a bit too hard and this added to the problem. From memory, I think theyre the semi-soft red ones, but would putting the softer black rubber ones help avoid this again, or is it just the bouncing around on the track which causes it and the rollers wouldnt make much difference...?
Sorry for all the questions, but am going to have a go at fixing it over the next few days so any advice would be much appreciated

Sounds about right
That looks like pretty minimal damage and a bit of flowcoat should do the trick. Flowcoat is just gelcoat with a wax in it that will dry hard. Before you put on a second coat of flowcoat you need to make sure you sand the first coat back a bit to get a good bond.
You can put a piece of masking tape over the area while the flowcoat is still wet and this will help get a smooth finish
