Rear tub rust above fender flare...any tips?

I just found this rust forming on my rear tub. as you can see in the picture i already tried to fix it temporarily. I used a wire wheel and grinded it down to bare steel. then applied 2 coats of primer and 2 coats of paint. This was 2 weeks ago. as you can see the rust is, of course, coming back.

anyone have any tips or tricks on what i can do to fix this permanently without having someone cut and weld?

you have to make sure you get ALL the rust off before you bondo/prime over it or it will just keep coming back

I would remove the flare, cut it out, weld in a piece of sheet metal from the back and use body filler to even it out. Then prep, primer, and paint.

Look up chassis saver by magnet paints (they make monstaliner). There is a video and some pics on the website.

ok now how about this on m front fender? you can see some pink bondo filling half the whole so take that into account for how big the holes are.

weld or replace fender?

I cut mine out with the grinder, used a piece of card board for a template to copy to the sheet metal welded in new sheet metal. 2 years later still good.

SquareLite & Dilligaf are right. The rust bubbling up on the surface is a result of what is happening on the backside of the metal. Cutting out the metal and either welding or glueing new metal in is the only way to fix it. Any other solutions will result in the rust coming back. Good Luck!
