Bodyshop was looking at my van after I got rear ended & dude made some comments about not worth fixing the damage & plus can't even be certified as is (to re-sell) cos, the rear wheel well seams are rotted & exhaust fumes risk thing..
Can't say I noticed before & not sure about the wheel wells (dunno if all metal) but upper & lower sections are joined & then appear to have a thick sealant type tape on top of the seam & definitely the seam is rotted away (looked like mostly the upper section of the seam).
Is this structural or just a matter of maybe wire brushing/grinding the rust at the seam, doing a fiberglass repair & sealing it up by maybe brushing on tar type goop?
