Advise on repairing rust
I'm getting the rust under the battery tray after my battery boiled over. I used NOCO and Ospho. Thanks to those that suggested the 2 products, they work great.
I only have access thru the rust holes and the 2 inspection holes I opened.I've gotten all the rust I can see & feel. I was going to spray primer and paint as well as I could but I started thinking perhaps some rust inhibitor I could spray might get better coverage but I don't know if it last very long. Any thoughts or suggestions? I'm pulling the fuel tank next weekend to see what I find.

Nothin' huh?
I'm sure I got the acid with the gallons of baking soda and NOCO and the rust with the Ospho. My concern is covering the bare metal I can't see under the tray. Any suggestions?

As far as I understand, if you can get it down to nice clean bare metal like you have, then you can just epoxy paint and then color over that. I guess the epoxy bonds strongly to the metal and prevents future corrosion.
If however, there are still slight amounts of corrosion present then POR-15 is the way to go. Just note that your top paint may not stick to the POR-15. You need to paint it with a Ti-coat primer to make it stick. Good luck, looks like you are doing a good repair.

That rust looks pretty ugly but the good news is that the metal you see inside that hole is in good shape. That is where the front suspension is mounted and is obviously very important. I am currently working on the same project and have not yet painted inside those 2 holes yet. There are a lot of nooks and crannies inside and I don't know how to cover them all with primer / paint. I thought about just pouring in a quart or 2 of POR-15 and letting it drain out the holes in the bottom. That should fill all of the seams etc. but might make a real mess otherwise. Anybody else with any good ideas ?

I haven't decided yet either. When I pour baking soda/water or ospho in I get alot running out & back by the stone guard.
Pouring in sounds good but will it cure properly? I'm thinking of drilling more or larger holes. Who knows what's going on under there? rust never sleeps
