ok i made my base for 4 kicker L7's rings. etc... ok i wrapped it with fleece no problem, resined it and did two coats even. come out and its dry but isnt stiff, so i cut out my holes to get to the inside to stiffen i thought and the rings start to sag. so i just put some braces back up to hold the rings in place. Now what do i do? keep putting resisn on the inside to stiffen completely or what?
