RAKA is a good, economical boat building epoxy. It resists blushing and cures clear. Use it for laminating as it or with additives to make gluing, fairing and filleting mixes.
Although we've never known the standard RAKA formula to blush, this special This RAKA 350 Non-Blushing hardener (with thin 127 resin) is slightly more expensive but is even more blush resistant.
Note: This epoxy is not UV resistant - it requires either paint or varnish for protection from the sun.
