I started to reply but hesitated… now I see a certain someone is going about some advice, I’ll lay out a little bit of what I’ve found.
First off, I have not applied any of this to an actual board due to cost. If I had a person request it, I’d oblige, however the material is pretty spendy to just whip out some boards for the racks in el surf shop.
So I made a few test panels. Since it was basic R&D I didn’t take process pictures, however it is all a lot more simple than people would think.
First off, lets jump to a laminated surface. It’s sticky and gummy to sand, however with some 40 then 60 grit sand the area a bit to where you want to apply the shell inlay material. Take measurements or whatever and make some reference points, guide points to get your desired end result placement of the shell inlay material. I used a pencil.
Now go ahead and move on and get ready for your sand coat glassing schedule. start with the areas that you sanded and use a brush to completely saturate that area first, but not too thick. Then place your shell material, use your guide points. This gets tricky, you don’t want your material to slide about, but It’s not too much trouble after you add more resin on and around the shell inlay material. Finish up the rest of the board. Sand out any raised area left from the shell inlay material/ extra resin in the shell areas. Shell material is available thin enough, that after a good sand job It all blends perfectly.
Most people gloss coat this type of project too, to really make that pain in the ass shell inlay pop.
I don’t use any glues or adhesives. Just the resin. One very good reason is that you don’t want any void spacing between the lam coat and sand coat with that shell material. Bubbles, delamination’s, and such. I just played around with scrap foam, and some logos.
Pinlines will be tougher, larger panels real tricky, and doing rail wraps that’s a whole’nother story!
All this information was gathered via composite engineers at my workplace and my Cousin who does very intricate shell inlays on mandolins, guitars, and fishing rods.
PEACE!
