I've never thinned epoxy for the firewall or wing saddle, just slapped the gunk on and spread accordingly. There has to be a way I can thin and brush. Sooooo, questions:

1) What ratio and %Iso Alcohol (or whatever) do you guys use?

2) What type of 'brush' do you use and once that 'brush' is used do you toss it or clean it with 'something' for reuse?

3) If you used 6/30 minute epoxy, does the curing time increase or decrease? Or for that matter, is it better to use a 6 minute or 30 minute epoxy for thinning?
