Catamaran gelcoat recommendations
Hey all.
Where is the best place in the Caribbean for a new deck gelcoat job. Looking for the best job at a good price.
I have a 2000 leopard cat in need of a new finish. I looked in Florida , but rates are $100 + an hour.

Gelcoat is generally applied to a mold. Using it as a paint after the fact is pretty rare, at least in my neck of the woods. Its just not designed for that. It doesn't flow right, it doesn't cure right in the presence of oxygen, this is why folks typically use paint, perhaps a 2 part poly like Awlgrip, for paint jobs.
You say its for a deck? Its probably not a terrible choice if you are texturing it with a nonskid additive.
Long story short: I don't know the answer to your question.

Re: Catamaran gelcoat recommendations
Have you considered just a cut and polish to revitalise your boat ?
Is there any particular reason you think the gelcoat should be reapplied?

Hi,
ya its 20 yrs of wear and sun, its powdery and you can see through to the fiberglass in many spots, and gelcoat if not regularly waxed will deteriorate. Of course people using soft scrub also hurts it, and the charter business ios full of crew using soft scrub or abrasive cleaners. I have a 2008 cat next to me , has a new gelcoat done looks good, however, if not done by really experienced people then it can be problematic. The local pro tells me it has to be done in sections, and prepping all the old surface is key, and its cleanlines before the coat. You cant have people walking over areas to be sprayed etc, dragging air hoses etc. Its a 5 or 6 section job and will take a month.

Re: Catamaran gelcoat recommendations
Benfain; I worked in fibreglass production and repair for many years.
Doing a full gelcoat re-spray is exceedingly rare because of the huge amount of labour involved.
Preparation is the easy part and not much different from prep for a paint re-spray. However paint dries to a gloss finish and gelcoat does not and will require wet sanding through several grades of paper and a cut and polish to finish to a high gloss. The success of this is heavily dependent on the skill of the operator and the quality of the materials along with ideal conditions to avoid any contamination, pinholes/porosity, orange peel or other defects. Further original gelcoat comes out of the mould with its gloss and surface tension intact which gives it a longevity a re-spray cannot replicate.
If you insist on a gelcoat finish pay the price of the local pro or go for 2 pack polyurethane.

Re: Catamaran gelcoat recommendations
An Amel 53 got its hull gelcoated next to us - in the water - in Rio Dulce Guatemala. I woke up one morning to a guy on a raft pushing our two boats apart while his partner sprayed the hull. A third guy was on deck mixing and keeping everything going. They then came back to sand and polish it out a day or two later. Crazy, but it worked well - it looked good at least until we left a few weeks later
This is one place I know that they do it for a reasonable sum.
Matt

Hey Red, I appreciate the advice and I think I'll be doing alexseal or awlgrip , whichever Elvis recommends, but not gelcoat. He recommended gel if it the cat was going to be used commercially, but did say that the 2 part finish would be a lot better looking. Thanks , experience is everything when it comes to this stuff.
