Hi everyone! This my first post on any auto forum. Over the past few months I have been reading many posts on this SPI forum, and from a novice, consider it the best. I am starting to work on my first car that I had in high school 51 years ago. It is a 1954 Chevy 210 post. I have been trying to learn all I can about removing rust and using SPI epoxy primer. The whole phosphoric acid debate is still confusing to me. I am sure I will have many questions in the future, but for this post, my question is: On pitted areas that are caused by rust , no pin holes and mostly solid, what is the process to fill and smooth the area? My thought is to sand blast the area, wash with a phosphoric acid, neutralize well with water, use W&G remover, spray with SPI epoxy, a day later use some king of glazing putty over primer and the rough metal area (RECOMMENDATIONS GLADLY ACCEPTED FOR BEST PRODUCT), sand, W&G, and coat again with epoxy. If more that 3 or 4 days, use a maroon pad to scuff surrounding primer before priming. Does this sound like a GOOD plan? Better ideas? Any need to sand primer before using glazing putty? Thanks!
