Rust on rear fenders

[theamazingkuskus]

So I’ve got a few bubbles popping up on my rear fenders of my 2011 Ram 1500. I bought the truck this year and immediately got it Krowned. Clearly the rust is coming from the inside out. I have wheel well covers but clearly they weren’t doing a good enough job. I don’t really have the funds to get a full panel replacement done but I really don’t want the rust to get worse. I was thinking of taking the wheel well covers out and giving the inside of the fender/wheel well a light sanding to remove flakes and then spraying a rust converter or rust killer and then topping that off with a spray on bedliner or rubberized rockerguard coating. Has anyone had any experience doing this and is it possible this will stop the rust enough for now? Cheers

I think the problem will be getting to the part where its rusted at, if you could get to it you could dand it down and paint it and stop it.

Drill a hole from ii beside the box. One that can be plugged with a nickle plated breaker panel knock-out plug
Wash that area out with wash wand. Dry thoroughly, treat a few times with rust converter, then treat several times a year with 80/90 gear oil. And put on some used fender flares and you can actually grease the currently affected exterior areas with grease before applying the flares.

Because once you remove the plastic wheel well liner you will see the huge metal support brace that is spot welded in place for the rear quarter / bed

The rust starts behind that support brace/structure and inside of rear quarter panel

Same issue in this thread

Spot welds in picture are for that support brace

Wow I didn’t realize that I haven’t had a chance to look under there yet. I guess the best option does sound like drilling a hole in from the bed. Sounds very similar to what Krown does but they don’t seem to target that spot.
What about the outside? I was thinking of buying some fender flares and taping off the area, sanding, POR15 then top coat and putting flares on that. Thoughts?
