Mix up a 50 g batch of West Systems 105/206 (slow hardener) and add 20g of Acetone. This is a good working reduction. Once you have your cloth positioned to cover the entire side of the airframe start from the center and brush a coat of the reduced resin out from the center. using the brush you can pull the cloth and eliminate any wrinkles and such. Just take your time brushing. You will notice with the reduced resin it's almost impossible to lay up too much resin as it is thin and runs off really well. Your just wetting and spreading here.

If your nervous, just keep breathing this stuff has an extended working time and if you think you really screwed up, just yank the entire piece of cloth off the airframe and start over. Also be careful of lose threads getting wadded up in your brush or laying across the cloth - you just want to work at a slow pace spreading the resin, trying not to make a big mess and just making things nice and even

Once you have a nice coat take the foam roller and start rolling the cloth out again starting from the center, you will start picking up resin, using a clean rag or paper towel, start ringing out the foam roller as you go. You will notice any small bubbles will go away as you push the cloth into the surface with the roller - you will also notice the resin forming a nice even layer with the weave of the cloth. keeo working the resin with the foam roller until satisfied that you have both rolled up all the excess resin and that you have created a smooth, level and even surface.

Between one fuse side and one side of the rudder I used appx. 40 grams of resin (just a guess I had a lot on the paper towel and foam roller and almost 8 grams left in the mixing cup)
