It's probably a moot point....some folks like one or the other. I have used them both, and I do like Aeropoxy better (and that's what I've used most). I went through a gallon of West with the "slow" hardener, and I wasn't sure it was ever going to cure at 72 degrees. So I tried the "fast" hardener, and it went off so fast that it concerned me enough that I put the cup on the concrete floor in case it spontaneously combusted! So it looks to me like West is more susceptible to exothermic reaction than Aeropoxy, at least the "fast" is, and that you can only mix small batches at a time for small jobs. It may be just the ticket for those who work out in the cold north, but I suspect most would use the "slow"....certainly for wing skins.
You could start by reading the instructions for both Aeropoxy and West 105 (with 205 "fast" hardener and 206 "slow" hardener for an idea for the cure times) and see what you prefer. Both of these are available on West's website. Personally, I find the Aeropoxy to have a less objectionable smell.
Whatever you use, I'd weigh it on a gram scale to assure that it's at the proper proportion. I'm not a big fan of the pump system, especially for small batches.
