Yes, that is my plan. I will buy the microballoons for the West Systems, and a gelcoat repair kit. Thanks! Daniel On May 8, 2011, at 2:40 PM, Judith Blumhorst, DC wrote:
Hi Dan,
Epoxy thickened with colloidal silica is as hard as a rock and difficult to sand and fair to a fine edge. Microballoons are deisgned to be used as a thickener when you need to sand and fair to a fine edge.

I have unopened west systems stuff and colloidal silica ready for my rebedding project. But I didn't think the colloidal silica was the stuff for thickening for this purpose. They seem to indicate using microballoons, or other products they have. So, the colloidal silica will work here? Do I have to wet out first, or just make a batch of epoxy, then thicken, then just apply it and fair it out?

Hi Daniel, sorry about the damage. Two part epoxy like West Systems or System Three would do. Although you will use little of it and you would need to thicken it with Collodial Silica (sp?) which West System also offers as part of the epoxy repair kit. Probably no reason not to do the fairing compound, just make sure that it is suitable for below the water line, most should be. As suggested the easiest way to match the gel coat or get close will be a gel coat repair kit. As suggested leave it proud (bulge or over filled) then sand down the gel coat to get it smooth. You just want to mask off the surrounding area as much as possible. I did a larger gel coat repair which is summarized at http://www.msogphotosite.com/RRBlister.html that may or may not help.

Montypals:
On my maiden voyage last month I didn't get the boat onto the trailer correctly, so on the ride home she bounced around and gouged up the bow a bit on a bolt on the trailer. So, I have an area about an inch long with the gelcoat gone, into the glass. Not through the glass. What is the best way to repair this? It is below the red stripe. I figure I need to sand it, wet it with epoxy, then fair it with more epoxy, dry, and paint? I've never done anything like that. Or, can I epoxy, and put some kind of gelcoat on the spot? Thoughts from the experts?
