Hi, I am ready to strip, prime, and body-fill my '69 Super Bee. Is there any body fillers that do not eventually shrink down the road? Also, I just put new AMD quarter panels on it, so I thought about using either USC Dura-glass, or all-metal underneath the final coat of body filler where the factory leaded joints are. Additionally, I would like a recommendation on an initial primer for the bare metal that would kill any rust that is lurking somewhere in seams or wherever. Thanx, Steve
