So I'm progressing right along...coupling coat and 3/4 oz mat: And used a roller to press it in the corners. Next up is a couple layers of 1.5 oz mat and polyester resin. For the final layer of laminate I'm planning to use this: http://www.fibreglast.com/product/Woven_Roving_223/Fiberglass_Mat

It will also make them much more rigid. Just for future reference, unless you're making it a van, you don't need to mould the window opening, you can leave it open to save quite a bit of time and money/materials when you add up all 4 doors Are you going to add any anti intrusion to the doors?

I used 1.5% MEKP in 1 gallon of gel coat...so going by the spec sheet (1% = 1 oz MEKP per 1 gallon gel coat), I used 1.5 oz of MEKP since it was a pretty chilly day. The spec sheet says you can add up to 2.0% or more depending on the temp. Hi B&D I am a complete amateur like yourself but I'm not sure about your maths here. I just checked and there are 160oz in an imperial gallon and 133oz in a US gallon. Which was it you were working with US or Imperial gallons? Either way you were not as catalysed as you thought. If I were you I would stick with grams and kg as the maths is much easier.

MEK would be the better stuff to use, or other proper mould cleaner seeing as you you can get it there. Soap and water will work fine too, just takes a bit more scrubbing.
