So yesterday i started some gelcoat im using composite envisions non waxed gc. Its about 3 weeks oldat best as i ordered direct from the manufacturer. My first coat i cleaned everything with acetone and brushed on the gc i also added wax. This first batch hardened i sanded smooth with 80g on a da sander. I sprayed my second coat today with wax. temp about 75 This was 4 hours ago still not hard. I thinned it about 10% and washed everything with acetone before spraying i catalized at 1.7% calculating before thinning with acetone. Did i over thin or isit because i used acetone as a cleaner instead of water?
