This is kinda sorta what I tried.

Fiberglass Resin Mold
Updated November 26, 2011

Supplies
1) Bondo Fiberglass Resin (Buy at Wal-Mart or an auto parts store)
2) liquid Hardener
3) Permatex Gasket maker
4) Metal pan from the thrift store
5) Pyrex measuring cup

Technique
a) Place the worm in the pan and then cover it with water so you will know how much resin to use. This prevents waste. Pour the water into the measuring cup to measure it. This is how much Bondo fiberglass resin to use...

b) Put a small strip pf gasket maker on one side of plastic baits. Glue the lures on the bottom of the pan.

c) Mix the fiberglass resin and the hardener in an old pan. Mix hardener and resin according to directions on the can. Usually this is about. ¼ tsp hardener for every 6 tsp of resin

d) Pour resin mixture into the pan. Start on the side of the pan and just let it float over the grubs and worms.

e) As the resin cools it will shrink away from the sides. Let it harden about 20 hours on a flat surface while in the pan.

f) Remove your mold from the pan. Take the worms and grubs out of the cavity.


Melting Worms

1) Use a Pyrex measuring cup and an old microwave. Do not use the one in the kitchen. Go to the thrift store and get one you can use in the garage.

2) Wear safety equipment. Long sleeves, face shield or goggles and gloves. NEVER USE water around hot plastics. It causes an immediate reaction THAT WILL CAUSE SEVERE BURNS!

3) Cut up the same color worms in the Pyrex measuring cup. Place the Pyrex cup in the microwave on the high setting.

4) Check the cup about every 30 seconds. Use welding gloves to handle the cup as it gets very hot. You can stir the mixture with an aluminum stir stick. Melt it until it is like hot liquid syrup.

5) Spray Pam on the mold cavities or use a small brush to brush the cavity with vegetable oil. This prevents the worm from sticking after you pour it.

6) Pour the liquid hot plastic into the molds. Let them set for about five minutes then remove your bait and put them in a pan of cool water to complete the process and cool off.

7) When they are cool you can use a fine pair of scissors to trim the excess overflow from the lure.

If this keeps up, I may have to scrap this and learn about injection. I am on my third can of resin at about $11.50 a can. As I said, I am pretty bad at this so far.
