Quick tips on stopping the rust on the cheap
It looks like you are makin good progress! Now add some sort of etch or Ospho and you'll be fine. I know it's not for everyone, and it certainly wasn't quick or easy. I have fought rust of all kinds for over 35 years and this was my solution on this Demon project: dustless blasting, metal prep, epoxy and then 2K primer. I've never had much long-term luck with any of those rust converters or encapsulators. I have used a product called Picklex-20 that is a similar to Ospho, then cleaned, prepped and epoxied over that with good results. I have also had great luck with POR-15 but just for covering and protecting rusted areas that will not be covered with a topcoat or see direct sunlight.
