he guys, im trying to bob my hard top this weekend. I have read the article by 4rnrRick,(and used the search button) and it doesnt seem that difficult. My problem is that i have no experience with fiberglass. i THINK i need to get the "screen-like" strips and some resin. then i THINK i keep layering the resin/screen/resin/screen/... is this correct? Rick and some others claimed to use plastic filler for the exterior. what is plastic filler? thanx for the help.
