Gel coat spray systems

[Roly]

Sorry Fanie, was quoting Landlubber.
I only have a sharp with a 2.4 tip gravity feed.
Dunno what a putty gun is. But I am blending gelcoat soon, where I marry deck to hull (rebate) , so I better find out.
Either that or spray with PU.

if your just doing that small of an area,,,and your gonna have to sand no matter what,,,wouldnt it be easier and faster to just brush it on?

Yeah probably......but I never get to use my gun.....
68' x 4" wide = 22ft^2 is a bit of gelcoat??????? (34' boat)
F@(K hope I have enough left!!!!!!
22 /11 = 2m^2 Yup, i have enough (1L @ 0.5mm thick)
Thx, 1much, for getting my grey matter 2 work.

Guess i'm gonna be doin some cuttin 'n polishin.
Will I have to put some clear resin on top to get the same lustre as the molded gelcoat???

Will post some pictures (if this sounds like gibberish), as we pop the deck tomorrow.
Yahhoooo....oooooo

nope,,you'll need to wet sand it,,then buff it,,,then you'll wanna do the rest of ya boat to match hehe

[Roly]

then you'll wanna do the rest of ya boat to match hehe

With my fingers and toes crossed..... if I can get it as good as the deck I'll be happy! (I haven't seen it yet but we buffed the mold for hours and waxed 5 separate times.)

a putty gun is just another name for a primer gun with a large tip you can buy a gun with a 2.0 or 2.5 tip and will spray gelcoat, a dump gun with paper cups is best, they also sell a dump gun with a contaner that holds 8 litres and is feed with a tube you just have t hang the bucket of gel higher ie gravity feed,

[Landlubber]

fibreglass jack, yeah, thanks mate, and also the question about sytrene making resin yellow, yes that can happen, just don't thin too much! Not needed anyhow to be like milk, we are not spraying finish coats here, just gelcoat.

Came out pretty good all in all. A little imprinting of faults in a mold (that hasn't been used for 25 yrs). The odd void under gelcoat where the fancy cornice molding is, and styrene attack on the transome where gelcoat was too thin.Our block off of the mold (transom/coaming) was cheap & cheerful so gelcoat work to be done there as well.

im surprised it came out that good,,,,considering the dude in the picture has feathers comming outta his ass hehe

[Roly]

Now that you mention it, he sounded a tad gay. Who cares, he was pretty good on the hiab and didn't "crack my deck."
BTW, check the deckmold b4 we got to it. Cow pats 'n all!

Thanks for all the help from you guys. Especially Waikakikin (jeff).I'm pleased with the transom mod.

[the1much]

now remember,,,,sounding gay is better then being,,hehe
and you should frame the "before" pic.,and leave it hanging in the boat,,,and do i hear a boat name emerging??( cow mold) hehe

Hi guy's you talk about small area spraying, what do you use with larger moulds, there appears to be many sytems on the market, internal mix, external mix, which is the best system. Also I agree gelcoat should never be thinned.
