Now back to some real work. I use aluminum fill epoxy surface coat,it make a great surface to mold off of.You can do repair to it if needed. But holds up to all of pulls out the mold.
Once the first coat is down let it tack up to were I can leave a finger print in it.Now go the second coat of surface coat. And let it tack up too.
Time for 2 layers of 2oz fiberglass,then 2 layers of 4oz fiberglass, and 2 layers of 6oz fiberglass. Also work some filled resin around the bolts too.
Get the mixer out 1 more time to help mix up the tooling dough. About 600 grams of each part,and mix till it is a lite green color. As you can see in 1 of the pics I use a board I made to roll out the dough so I can get it to 1/2" thickness.
Keep working it out till the whole thing is covered with this dough. If you did not make the right amount of dough just make some more and add it.
Then last thing to do is 1 layer of 6oz fiberglass and let dry over nite.
