Do I Need Another Product With This?

  • Is there good paint on it but you just want to paint over? No. No primer is needed.  You can use a scuff pad, wipe that clean, and then lay down your base coat.
  • Is it bare metal? Yes. You will need SEM Self Etching primer first. The self-etching primer bonds to steel and aluminum and you shoot any other primer over it. You can buy the SEM Self-etching primer in a bundle with the Flex and save $4.
