Anyone got any experience with FLOWCOAT . Looking to paint my hull bottom .Its a pacific 22 . Would it be easier to paint flipped over.

Contact neugent on here he's a genius with hull refurbishments he sprays and look like new when he's done

100% easier to do flipped over re gelcoating isnt for the faint hearted it means a LOT of sanding afterwards to get a good finish. Far easier to spray with a two pac paint

I’ll tackle any gelcoat/flow coat repair, but there’s no way I’d do a whole hull. If you are applying it by hand as opposed to spraying, it will be going off faster than you can get it on.

My local body shop guy says it will fit in his oven. He reckons that he would put four sprayers on the job each with different strength hardeners in the mix. for the different profiles on the hull , reckons if it all goes to plan it would Flow . What happens if it all goes against the plan. whats the alternative .two pack paint was mentioned.

flow coat has wax in it to make it cure in air so coats would delaminate if you spray gelcoat it would have to be vacuum cured thats why two pack is used not an expert as i say neugent is the man he will advise.

Thanks. Its definitely one job that you would like to get right first time.

Obviously I don't know what condition it is in but could you not use the marine equivalent of t-cut to smarten it up rather than re gel coating / painting it?

or as an alternative:

Car polishing compounds work absolutely fine on GRP.
Just be careful working on swage lines/sharp edges with compounding mops as you can go through gelcoat surprisingly quickly.

What's the reason for wanting to refinish the hull?

You do base coats in gelcoat then add wax to the mix to make the final coat cure. Flowcoat is pretty much the same as gelcoat with wax added or you could spray on the gelcoat then spray a coat of flowcoat to make the gelcoat cure.
I wouldn't be spraying different strenght hardner mixes together it could cause problems if different strengths overlap at tge wrong time

every day a school day didnt know you could spray flow coat although it is a different animal to the brush applied it seems much thinner so prep will be key

thanks for all the replies. The hull gelcoat is yellow and has about twenty small repairs to be carried out . I have rebuilt the transom and the deck and want to finish in battleship gray. I am not looking for a polished hull as I don't have the need for speed. Economy is not a major factor either . But if I am going flipping it over It would be nice to get a fairly good finish

If it's going in the oven...

Tubes are coming off?

If you are going to flocoat it by hand use a roller.
It allows you to put it on thick and fast with half decent finish.
I did a couple of seat pods 20 years ago and they are still going strong

Get it sprayed. As per the above, Nugent is your man as he specialises in exactly this. His workshop is in the Midlands somewhere.

beamishken · 08 February 2020, 12:19

Nugent sprays most of his stuff with two pack paint acrythane from hmg. You can use gelcoat either sprayed or rollered, ive used both and the two pack paint is 200 times easier & just as good in most cases especially if the boat is flipped upside down
A reasonable sized hull like this I'd definitely go the two pack route

mikehhogg · 08 February 2020, 18:47

Its looking like two pack paint, Ill take a few pics when the hull is flipped. before and after.Thanks for input

nugent · 09 February 2020, 05:21

Hmg polykote mu primer
Hmg acrythane G4 top coat

Its great gear and will not fail if applied correctly
Do not add any rocket or speed enhncing products

Prep with 180 you want a good bond. Neat mu primer mixed with Hardner to spec only. Sands up a treat

Nugent that's a great bit of info for me, something you wont get on Google lol,thanks

Philip Hodson · 09 February 2020, 10:05

I sprayed my pac 22 with ICI 2K in 2004 & that held up well to when I sold it
last year.
