I'd like to coat the bottom of the chassis of my 70 Camaro. It will be pressure washed, media blasted. What are your opinions for a primer. 2K or Epoxy? Do I need to use an Etching Primer on the bare metal?
I like the epoxy as it gives a better seal against the elements..and I epoxy prime everything before it goes together..I know SPI epoxy is direct to metal and requires no etch..makes it a real easy product to use..these days I am using bedliner on the undersides..makes a quieter ride and keeps the rocks away..
