evil BLUE spackle?

A friend brought me an already-shaped S-core blank that was obviously a second/reject, to see if I’d glass it for him. There are about 2 dozen pukas in the deck clustered up by the nose that make it look like blue swiss cheese.

Anyone ever worked on something like this? what did you use to fill the holes? The board has been shaped down so thin that I can’t really salvage any foam (although maybe some foam dust) from elsewhere on the blank.

I’m planning on RR epoxy (even tho I have no Add F yet) and 2x4 S glass w/glass on fins. He gave me the metal vent (nice blue anodized thing) but I’m also unsure on when to install such an odd duck. Pre-glass I suspect?

If I’m reading this right the the foam is blue, glassing clear

Personally if the holes are small what I would do is just fill them with plain clear resin before glassing, spakel or a foam dust resin mix will not match the colour and it will look really ugly.

Sounds like the holes are located in one area so you could always cover them up with a little (or not so little) painted design/artwork over the top of the glass.

As for the vent plug its difficult to say without a picture, but if in any doubt it would be easier to install it after the lam and add a patch over the top before the fill coat.

Paint it with a couple of coats of good acrylic house paint with 10-15% extra top quality acrylic added.

I don’t use vents because I use #2 high quality EPS, but I think you do them after the hotcoat, like you would a leash plug. But I’m not the one to ask.

I prised out a complete vent as I couldn’t undo the centre part. It was glued in after board was hotcoated.

Still not been able to get it apart. Got a spare one?

The answer may line in:

  1. Coloring the spackle with an appropriate water based color

OR

  1. filling with any spackle and overlaying artwork either a spray or a rice paper print to camouflage.

Keith, I pieced together a couple pieces of blue Dow foam a couple years ago. The seam wasn’t perfect, so I added some blue acrylic paint (Liquitex) to some “Fast and Final” spackling compound until the color was close. It worked pretty well. Not perfect, but better than a big, gaping hole.

When I worked in a factory that was making the S-Cores, the vent plug was the last thing to go on the board - after it was glassed/hotcoated/sanded, a hole was drilled w/ holesaw and it was stuck on with a little bit of 5 min epoxy around the bottom lip.

thanks everyone - appreciate the input… a little knowledge can be a good thing, despite being dangerous! I’d love to hear more but I think I have enough to go on… I told the guy “low expectations” so that’s my story and I’m sticking to it!!

Keith, acrylic paint and epoxy/microballoons/foam dust for the filler; match the color a bit lighter and then add the hardener. Get it as smooth as possible while soft so you don’t have to sand. On the S-core vent, I get weekly calls on adapting GoreTex vents to these.

Keith…

you build high quality boards…you have a very good method…you need poly resin…

Maybe the Seal Slayer can help you…I just glassed another board with RR…in my makeshift set up it took over 2 1/2 hours to cure per side…I have a big space heater…might want to wait until summer…Don’t waste your time with DNA wipe downs. Lam and hot coat both sides in less than 24 hours. Try not to go below 65 degrees F…I don’t post cure in an oven…I put the boards in the house for a few days after glassing…You know where to find me if you have questions…
