I am beginning to work on the body of my ’72 Monte. I am wondering if there is a primer in a can I can use. I am only able to work on the car on the several hours at a time. I am planning on stripping it in sections and want to can spray it easily to keep surface rust off of the car, as it will take months for me to complete my work. Once I have the entire car stripped I want to sand the entire thing and and then primer the car correctly. Is there a aerosol primer you recommend for something like this? Would you use a standard primer or an etching primer? Any advice is appreciated.
