I hate the stuff, but it was designed to line ethanol-based auto fuel tanks at your local Zippy Mart... +++++++++++++++++++++++++++++++++++++++++++++ The catalyst to activate the vinylester resin can be adjusted for the ambient temperature; use more or less catalyst: 0.5 cc catalyst per 8 oz resin for 20 minute working times at 100 degrees F versus 3 cc catalyst per 8 oz at 60 degrees F.
