- I have a 6 year old Toyota with the typical crummy Japanese
- paint job (the rest of the truck is great..). I've got
- some nasty rust creeping through the rear wheel-wells that I
- need advice on.
-
-
- Here is a cut-away view of the right wheel well seen from the rear
- of the truck. The well is formed by 2 sheets, one is the side
- panel of the truck, the other forms the top of the wheel well.
- The two sheets are folded together at the bottom and crimped
- (spot welded?). The outside sheet is rusting badly along the
- bottom 1/2". It looks like water has been creeping in through
- the seam and rusting the metal from the inside out. While the
- outside of the truck shows almost nothing, probably 50% of the
- steel in this 1/2" strip is gone -- you can easily put a knife
- through the metal. Above this area, the steel is fine.

- My best idea is to get inside from above (not too hard in this
- truck) and clean things out very thoroughly. Then a coat of
- rusty-metal primer, and then fill the whole area with epoxy
- or bondo or something. When this set up, I could then attack
- the outside, remove all the rusted garbage, putty and sand,
- prime and paint. Is this the way to go, or is there a better
- way to do this?
-
- Thanks for any feedback! I don't want to spend a couple of
- weekends on this and have an even worse problem next year!
