Prepping my car to paint the inside and bottom with POR-15..... In rinsing the bare metal from all my hard work, immediately as it was drying it started to "Flash Rust." Is this OK to paint either POR-15 or Epoxy Primer over the top?
there a product out there i forgot what the name is. but you dulute it with water 13 to one i think , and spray on fresh bare metal. it prevents flash rust. and etchs the metal , which make a good prep for paint, i used it on a frame and firewall with very good results also rust is a bacteria after you cut off its air supply its dies, but i still would not want it under a high end paint job
