Ray, The catalyst mix (MEKP) is variable and should be varied depending on the temperature and the amount of promoter in your resin. Since you buy the resin already promoted, you don't know how much is in it, so you have to do some test batches to find the set time. Do some tests with your Vinylester resin and the MEKP to find the ideal working time for the resin at the temperatures you're working in. Keep in mind that it is exothermic, so larger batches will set much faster than small batches. Slowing down the cure time a bit isn't going to hurt the strength of the Vinylester resin.
As for actual mix of resin to Flox, just keep adding flox until you get the consistency of peanut butter. Again, do a couple of small test batches to see how it works before doing the actual deed. It's simple and you'll learn quickly.

Spars and ribs are done. Ready to mount to the fuselage. Have the video re: setting the dihedrahl and think I can follow it. Question #1. When I ordered everything it came with some flox to stiffenup the mixture when I start using it. When I check the video it looks like it has been mixed to a consistency of peanut butter (not free flowing). So what is the formula? MEK to resin is 2%. How much flox? Question # 2. Can I use a little less hardener? 2% sets up fairly quickly. If I dropped it to 1.5% would that buy me more application time but not weaken the final product? Any advice on anything even remotely connected will be appreciated. Any tricks or tips that could make the job easier/better? Intention is to place the bottom skins only. Then will set the aluminum fuel tanks, run wires for lights, set up tie downs etc. Top skins and final ribs will be in the future (hopefully near future). Thanks for the response.
