The RB is made to go on in 2 coats over clean metal - either bare or rusted, as long as it is free of oil, grease and loose particles. No primer is needed. It must be 2 coats as the 1st coat will penetrate the rust and it produces a gas that will make microscopic pin holes in the coating. The 2nd coating seals it. It can then be top coated with paint. The 2 products that I have used are the original formula and the automotive formula. From what I remember the automotive laid down a little smoother to provide a better surface for a smooth top coat of color. The original seemed to cover more area with a thicker coating. There is a ton of info at the RB web site. I would say looking at your pictures, you will need to spend a lot of time cleaning down to bare metal as best you can, then replace (weld in) new metal into any holes, then clean some more, then coat with the RB and then top coat. Lots of videos too on Youtube.
Trimmed out that hole to solid metal and used a repopped Mustang inner fender to make a patch piece for the hole. Welded it all in using a fresh battery tray as a jig to hold it in place while welding. Then cleaned and coated it with the RB. There is an old thread on here with the repair progress someplace.
Good start. Looks like someone patched in new metal at one time there. Hopefully you will not have any big holes to deal with.
I did the battery box and never primed it a year ago. So that’s my mess. I did passenger floor already. This is a learning curve for me. Never did this type of build before.
That needs to be sand blasted , only way to do it right. It will be worth it , and you will save a ton of time. Hopefully you know a good sandblaster and have a way to get it there.
Wow Mavericks suffering from the same battery tray problem ,yes I use Eastwood products like them very much ,you need to clean all the rust and use this 3 products, Good luck
Hello after you cleaned the metal did you use any type of converter And encapsulator or just the primers you showed. Stockish
Hi yes I clean the metal the best I could and apply the epoxy primer , that was my preference choice, when you have rust no matter what you do is there and it will shows again in time , and epoxy for me it will last long better
Was common for batteries of era to occasionally belch in hot weather. The lost acid munched on battery trays & inner aprons. Common issue on most vehicles.
