Fibreglass release agent

I am making a small cover using a 'male' mold....What I need is a cheap release agent....Something from under the sink, or from the car wash bucket.....Part will be laid up with glass cloth in two layers.... Thanks in advance....

Johnson's floor wax - the paste version in a can. I also dip drill bits in it when drilling through carpeting to keep the bit from grabbing the carpet fibers, but it's a great mold release, too.

If you don't believe that, then MeGuire's has a mold release wax that (supposedly) works well, but I've never used it.

Short of those two (I've actually used Johnson's) you could order a mold release from Jamestown Distributors in Rhode Island, but any local auto paint supplier should be able to provide mold release products.

Thanks Gordon, I was hopeing some one had done something similar....Floor wax it is......

Just heard from a friend that "Sex Wax", which is a wax for the top surface of surfboards, supposedly works as a mold release, too, but I've never tried it (and I bet it might be harder to find in Gainsville, GA.!!)

Yeah...With the bottom of lake Lanier poking up all over the place, there is not much surfing going on....Thanx for the thought though...

Sex Wax ehhh.....? Gordon, we never knew!

I have tons of it I'll mail it to you. Besides surf shops you can get it at the local liquor store here and it smells good!

"SEX WAX - THE BEST FOR YOUR STICK"

Straight from the can label, circa 1970.

leon , you could also use 3m overspray masking liquid , its original design was a mold release , spray it on with a cheap paint gun and it washes off with water when done , water also helps you get the part out of thr mold a little easier .

Wrap it in plastic wrap.

Boat builder paint their molds so they are pretty slick for repeated work ..
Then they rub on a good coat of bee's wax on the intire mold surface and then prceed to lay the fiberglass.

To release they blow compressed air at a corner crack . Your guess is as good as mine on how long to leave the fiberglass to cure before blowing the mold?? My guess is 4 hrs

Part has been laid up and removed from male mold.....Jhonsons wax did not work quite as well as I had hoped, but all in all it went prety well.....Hope to have the results at Carlisle......Remember my amature status as paint and body guy.....

Thanks to all......
