Well, you shouldnt really hijack someone elses thread like this (this should be posted in one of the HELP stickies), but fiberglass resin will run you about $35, fiberglass cloth will be about $8, and you can get some cheap brushes for the resin for like 50 cents at home depot. But again, please put questions like this in the stickys. Or better yet, just look at the noob list sticky by Ithica which has the answers to what you asked and about everything else youll need for a build.
