Guys I have been doing some body work and the good news is its alot more solid than I originally thought. The bad part is that the trunk pan and underside has alot of surface rust. Under the surface rust their is alot of rust pits. I have been using a cup brush on my angle grinder to remove most of it. Then I apply naval Jelly and rinse off. Is their better way other than blasting. i even used CLR with decent results. I dont want this rust to come back and I dont believe on miracle products.
