I would never want to still be applying epoxy as it starts to kick. I'm in the small batches, more coats camp. Seems to let me I get the weave filled more evenly with no runs, no more than is needed and doesn't need much sanding. I think it takes less time in the whole process and probably less weight. I would only try high viscosity for very thick coating of flat pieces I could coat while level. You can apply more to spots where it doesn't cover but the only way to get it off where it's too thick or sags is more elbow grease. You should get their manual, very good info.

: That's the thing I'm looking for - increased viscosity rather than more
: working time. Or to put it another way, more time spent in the viscosity
: range I like. I saw that in the book, and Vaclav's site mentions it, but
: both are a little vague, so I was hoping somebody had a positive
: experience to report. I get plane surfaces to fill in two coats, but chine
: edges seem to take another couple of coats to get filled. The thicker
: stuff late in a batch did great. I'm hoping for thicker from the start,
: but a similar to normal pot life. I've sent sys3 an email for info, and
: will try a test in the next couple of days. Maybe there is no free lunch,
: but who wouldn't skip a coat if they could?

: Then again, maybe I'm trying to overfill. Sanded an area that still showed a
: hint of weave, and got it smooth before I hit glass. OTOH, there are areas
: where I'm sure I'll hit glass first. Those I'll be going back over. Still
: needs more buildup around a the veneer work anyway.
