My tenders looking a little shabby, I think it has been painted in the wrong paint before, it just flaking off. I know there are some fibreglass experts on the forum so thought I'd ask about the best paint.

I thought it was better to not paint it if it has a gelcoat finish. I have two fibreglass dinghies. One is painted (by previous owner). The other one is original gelcoat. For the painted one I think he said he just used normal outdoor gloss paint. Its coming off.
I am by no means an expert on splitters so please ignore.

My tenders looking a little shabby, I think it has been painted in the wrong paint before, it just flaking off. I know there are some fibreglass experts on the forum so thought I'd ask about the best paint. I've had great results with this. www.smithandallan.com/products/industrial-paint/1631-protegalac-abv-90-/Knock it back with 180 grit, clean with pressure washer and sugar soap, quick go over with tack cloths. Apply in 1' x 1' squares with aa 4" foam roller, brush out with a 3" foam Jenni brush. It doesn't keep a wet edge for long so it's a good idea to do it with two people, one rollering one tipping off. Fast progress can be made like that. Dries quickly too. International toplac is good, but it's imperative you use prekote to isolate and prime before applying toplac. I use toplac on our superstructure as it keeps a wet edge longer, it's too expensive to use on the hull and no better than the abv 90 apart from the wet edge factor. Not an issue on easy flat surfaces with not a lot of cutting in to do. Abv 90 needs no such preparation and will go straight on to a clean well prepared surface without isolating coat, primer or undercoat. I've been using abv 90 on ours for 8 years and am pleased with the results, previously used rylard on another boat and wasn't that impressed with it. |

Is it worth it for a dinghy?

I'd say so.
1l will be enough.

I think I'll put the opposite view point up. I think it is much more the preparation than the finish that ensures longevity. My suggestion would be flat it back properly making sure there is a good key. It's important there is not the slightest trace of any previous polishes (especially silicon based ones !) Paint it with an ordinary gloss paint putting it on with a radiator roller with a quality fluffy roller. You can brush it out if you really want a glossy finish, I don't bother I like the slight eggshell finish of the roller. Shapfell has been painted this way (hull , cabin top is still gelcoat) all the time I have owned her and I think she looks quite presentable (B & Q's outdoor gloss ) it lasts well enough. I have never had problems with it peeling and it seems to last at least two years without needing attention.

Thanks for the advice, it's not a job for now. But I will definately paint it this year.

The boat that I have which was painted with gloss is not subject to peeling - the paint is coming off due to abrasion.

The ABV 90 is an industrial coating that is way cheaper than International. |
