Can somebody tell me how much hardener to mix with resen.
The box says 7 drops a table spoon but the stuff hardens in like 5 min. I think I'm do'ing everything wrong.

The stuff hardens in 5 minutes. That's normal. You can reduce the hardener a little, but if you go too far it won't harden at all.

7 drops of catalyst to a table spoon of resin :eek: That's way to much hardener. I put that much hardener in a cup of resin. And I mix it pretty hot. :)

So you think I should use 7 drops to a cup.
It's for a ported sub box in weel well.

Seven drops for a cup.....you have to define 'cup.' The stuff I use recommends 12-14 drops per ounce.

Also, get a dropper so you know you're using exactly a drop.

wow what kind of resin and hardiner do you guys use. For a small 9 oz. cup i use about 50 - 70 drops ( depending on the weather ). it usually takes around 5 - 7 minutes to harden.. again depending on how hot it is outside.

I use the plain All-Purpose Fiberglass Resin from Home Depot....

It depends on the type of resin. I don't usually measure it to be honest. I mix it by eyeball. it takes a little getting used to. I have been playing with the stuff for quite a while. :)
