Which Gelcoat?

I've loads of little chips and scratches on the underside of my hull and a couple of large chips (where the hull and transom meets) that happened when the RIB fell off of the trailer last year.

Now before everyone starts "shouting" use the search, which I've already done I'd like to ask the question:

What filler is best for repairing this damage?

I've seen Plastic padding Gel coat filler and epoxy filler and a number of other ones, but is good old Gel-coat mix still the best material to use?

What do you guys use?

Andy

Andy I think yours is a posh BWM (Scorpion even) and has a white hull so the Plastic padding Gel coat is what I would use. Should get a decent finish with it.

You might want to add a bit of white pigment to it. It tends to cure to an off white colour without the pigment.

As an ex owner of an indispension roller coater trailer I am used to gellcoat repairs.

gel coat repairs

i've used Plastic Padding before and it polishes out really well, if really deep ding then filler first then the gel coat
you can go down the route of contacting the manufacturers and they may be able to supply you with the original gel coat .

For anything other than tiny chips I pop down to my local GRP laminator and get some nice fresh gel and mek. I personally don't favour flowcoat or wax additives as it makes it a hassle if you want to re-apply any gel before finishing. I just put straight gel on and seal it up, either with tape, or for large areas I spray some PVA release agent onto it. The PVA especially is good as it seals the (wax free) gel so it cures properly (no tackiness) and just washes off when you're done.

I've heard about sticking tape over the repair untill it cures, is that to stop the two part mix from dripping out when it gets warm or to stop the air from getting to it.

Just ask any GRP laminator for PVA release agent. Available by the gallon in white and blue. I like blue 'cos I can see it to wash it off when the job has cured.

I used it when I re-gel'd the sharpe. Spray the gel on, wait until it's just starting to go off, then spray the pva on. Spray loads on until it covers everything and is running like it's just had a vindaloo.
