Did the same with POR15. No need to sandblast to get the final little shiny 
rust spots out. POR15 works better if there is no flakey rust, but rust is 
good with POR15. 3-4 years later just fine. POR15 is heavy enough to fill 
the pitted area. If you are going for concours then it's not the answer. I 
have a spot sandblaster (media) that recovers the media and reclaims for 
reuse. Gets the small spots without having to turn on big bertha and make a 
mess. They are available at Harbour Freight. I got mine at Eastwood at a car 
show where they were a vendor.
