Fiberglass questions

[WildBill9000]

Anybody know where I can get black color agent for gelcoat repair? All I can find are the kits with stupid little tubes. Im almost done with my ski, but I'll have to replace the color agent I've used.

Also I keep getting porosity in my repairs, how do I get rid of that?

Any other fiberglassing pointers (that are not readily available on the net)?

what a quart of gelcoat or a quart of the color agent?

Find a tub of black pigment with some white gelcoat and keep adding black pigment to the white gelcoat till its right.It will take alot of mixing to get the pigment to mix in with the white gelcoat.

black gelcoat

Thats if he can't find any black gelcoat.And if your working with fiberglass in cold weather its best to do the work in a warm building or use a heat gun to warm the pitched area after you have applied the fiberglass and resin.That is so the resin don't run out of the fiberglass and make air pockets.The colder the weather the longer it will take the resin the cure,the warmer the weather with the right mix of hardener it will work fine.
