correct resin to use making tweeter mount

I am new with this fibeglass and am going to put my tweeters up in the a piliars. I have seeen some great picks of others doing this procedure using a piece of thin wood glued to the pilliar holding the  tweeter mounting cup and then putting pantyhoses over the intire area for the fibeglass to set and makes a great factoy clean look. What type of resin do I use with the fiberglass and will i need any hardener sorry its my first time! Thanks Kris

any other Advice would be great!!!!

Polyester resin, MEKP is the hardener (1-2%)

You might want to use something thicker than pantyhose (Like fleece) so your finished part comes out srrong enough. Practice fiberglassing on something less expensive than your car before you tackle you A-Pillars.

pantyhose would probably not be a good choice because there is alot of rubber like material in panty hose...(spandex like) because resin will eat through rubber if there is a large enough percentage of it...so try to keep it to a mainly cotton/fleece material...i ususally use material that is about 95% cotton, 5% spandex, that way it is stretchy but does not have enough rubber to react with the resin

...ever noticed resin can get HOT when mixed up...well ever noticed that happens to Spandex when it gets hot...
