Yes, I sanded the nonskid with 60 grit on a 5 inch orbital. You do not need to take it off completely, just get it 'mostly' smooth. The Kiwi-Grip fills really well, and I'll bet there are folks out there who rolled it on without sanding and had no problems, but I didn't want to risk the nonskid pattern showing through. I did prime it but I don't think it is necessary. That kiwi grip bonds like the dickens to just about any surface. I'd give it a good go with a sander and just wipe down with acetone and roll on the kiwi grip, take down the roughest part of the non-skid but its ok if there are still small dimples.@CloudDiver : Thanks-- yep not wanting to build up surface as much as trying to smooth out what was a messy blotch of resin and cloth.
And a totally unrelated question: but when you re-did your decks, and especially the hatched original non skid portion --I assume you sanded that gel coat smooth? Wondering also if you took the Gel Coat clean off the surface or just took it flat and faired/primed over as necessary. Struck me yesterday while filling a few holes that I really haven't thought through the deck surfaces.
I think Colloidal Silica is not recommended for below the waterline. West makes a high density filler that is for use below the waterline.thicken some micro fibers or colloidal silica
You're correct, I have head that same advice as well... BUT, if you think about what colloidal slice is composed of, water will have no effect on it. I think that's a hold-over from when cabosil was the industry equivalent of colloidal silica today. Anyway, there are so may layers of epoxy and epoxy barrier coat over the top of that layer it is reasonable that water would never get to that level. All said and done, I don't disagree, better safe than sorry and use microfibers. I imagine that @pclarksurf has finished the keel fairing by now.I think Colloidal Silica is not recommended for below the waterline.

Can you elaborate on that at all? I was looking for just such a filler at WM.com last night, and saw nothing with "below waterline" specified. I suppose I could call them?West makes a high density filler that is for use below the waterline.
