: I'm currently stripping two kayaks, a 14' and a 17'. I've only done small
: fiberglass jobs in the past. I started to put together my list for mail
: ordering my epoxy supplies from System Three and I have a question
: reguarding how much Phenolic Microballoon and Silica Thickener I might
: need.
: I understand the microballon and silica mix is used for end pours and
: filling/ fairing agent on the deck and hull.
: I can get both items in 1 quart or 5 quart quanities, I'm thinking 5 quarts
: may be way too much. Think 1 quart of each might do the trick?
: Any input would be appreciated....
: Thanks

I would think 1 quart is plenty, it goes a long way. The microballons are purple and sand easy but you don't want to use them unless you are going to paint that area. They also have the least strength as a filler, mainly for easy sanding and filling low spots which you will paint over. After you sand them, you open the little spheres so a light coat of epoxy is next to fill the little holes.

1 quart of silica would be plenty also I expect, but if you are going to building boats for a while you might want more. I use it a lot to thicken putty so it will not sag or run.
