Rust removal and priming

I am removing body parts from TR6 to get as close to rust beginnings as possible. I will sand blast these areas because they will not be seen by the public. I will do small areas at the time, and do not want to mix up a batch of epoxy primer and spray due to the small amount needed at the time. Have any of you had a workable plan you used to blast, clean and prime small areas until it was feasible to mix up the epoxy? What brand primer did you use (was it a rattle can or brush-on?)? If you followed-up the preliminary priming later with an epoxy primer was it compatible with the first primer, or did you have to remove the first primer before finishing? /ubbthreads/images/graemlins/confused.gif At my age I only want to do this once, and I plan to pass the TR down to one of my kids.
 
I forgot to mention that I do not have a shelter, the TR stays outside, and is covered with a poly tarp. I keep it as dry as possible.
 
First of all, sand blasting sheetmetal is best left to the experts. It is very easy to deform the sheet metal even when lots of care is taken. As far as protecting small areas after they are cleaned for a future re-coat with an epoxy, I think you will need to remove the previously applied primer. You can find a lot of answers at https://www.autobody101.com/

Good luck
 
ecutr6, I use a product called ospho after I sandblast small areas. It turns the metal a grey color and preserves it till I am ready to put an epoxy primer over the combined entire area. However my project gets stored inside, I'm not sure what results you will have, being that yours is out side. You may want to spray each area with a primer sealer until your ready to spray epoxy primer over the entire area and you may have to lightly sand the entire area just before spraying the epoxy primer. As for sand blasting. My experience using a small 5 hp air compresor for sandblasting, does not put out the high blasting preasures that the comercial blasting outfits put out. Our small blasters only have 1/8 inch gun nozzles and much less preasure. Of course you never want to hold your blasting gun on any one spot for more than a second and keep it moving back and forth. The out side body panels with the large flat areas are the ones that are the most critical for risk of warpage. Just keep the blasting gun moving back and forth.
