Hey everyone! Got my whole front end stripped and getting ready to wire wheel the cowl and firewall area, and I have a few questions. I'll be painting everything with just SPI epoxy primer for the satin black look and durability of the epoxy. 1. Should I completely remove all of the existing seam sealer, and replace with fresh sealer? 2. SPI epoxy directly to metal, or spray etching primer first? 3. When (in the painting process) do I apply the fresh sealer? 4. Lastly, can anyone recommend a sealer? Thank you!
