Polyester ISO Tooling/ Laminating Resin

Very happy with resin Good fast saturation of glass. Mixed MEKP @ .75% (0.0075) and that gave adequate time to lay the glass and get the bubbles out.

I've been using Vinyl ester resin and veil cloth for stress crack repair, but Vinyl ester seems a bit brittle, so I'm trying ISO resin for a bit of flexibility. So far so good, t wets out well and cured with less tack than I expected.
