I live in the northeast – I work in an unheated garage and it’s finally warm enough to sandblast the bottom of the car, but not yet warm enough to paint it. Is Metal Wash good enough to apply to prevent flash rust until it warms up enough to apply a paint coating? The literature says Metal Wash prevents Flash rust for 3 weeks.
What coatings would you apply after sandblasting? PRE followed by Rust encapsulator followed by Chassis Black Paint?
