Re: Finishing a body repair
Your steps are about right, except...
Grind, scrape and wire brush all loose rust and debris until you can't get anymore debris to come off by scraping, brushing or grinding.
Ignore everything you see or read about any rust convertors or "paint" and only put on 2 part epoxy. All other tinctures will fail and rust will occur.
Weld thru primer will help keep rust out from between the mating surfaces you are welding. There is no perfect cure for this area.
Once all buttoned up, you can spray a cavity wax into those hard to reach areas. This combined with a 2 part epoxy are as good as you'll get.
Good luck. Thanks for posting pictures.
