5 John, Timothy, and Mitchell worked late into the night on day one and into day two in order to get the remains of our car blasted and primed. We were able to take it back to the shop by 3:00 on day two. Once the old paint is removed, the body will flash rust in a short amount of time. The best way to protect the car is to apply an epoxy primer over the bare metal. Epoxy Primer is a two-part primer consisting of the primer itself, and an activator. It can be used as a direct-to-metal primer (DTM) because it has excellent corrosion resistant properties. Depending on the brand you use, it can also be reduced and used as a paint sealer. However, it is not meant to be sprayed over rust. It is not a neutralizer; the metal must be clean. Epoxy primer will adhere to all properly prepared metals, and can be used underneath body filler.
