Temporary Cancer Fix

[RadarRider]

I'm starting to develop some cancer on my right rear fender well. It started off as a minute bubble now, after about a year, it's cracked & developing more bubbles. I had done an oil pan replacement on a friend's '97 PSD & as payment, he was going to fix that spot. Problem is; I waited too long & now the weather's crappy. What can I do in the meantime to prevent any more damage until next spring?

I got it BAD on both sides, but all of the auto bodies wont touch it till after winter.

I had that issue on the bed and got the whole thing redone for about $800 over the summer

i would say clean it up best as possible then hit it with a good sealing primer/rust killer primer that should atleast slow it down

poor some boiled linseed oil over it, thats what all the farmers do, it will dry in a a few days and will stop rust. its at home depot next to the paint thinner

Once you have the blisters over the wheels there is no good fix except replace the box side. My 02 has the same problem and now it is a matter of saving up for 2 new boxsides. This was a crappy design on Fords part, 2 layers of metal with a foam in between that will hold moisture and dirt. I have been doing collision repair for 20+ years and have seen way to many of these designs from all the manufacturers.

My box on my truck started bubbing then next year it holes were visible.... I bought a new box and painted it. With the old box I wanted to see the extent of the rust, poked at the rust seeing where the strong non rusted metal was... I went alot further then I expected. The rust was about 1-2" visible, then under the paint it went aother 2-3" in areas.

But if you try to stop the rust, you do the inside of the panels. Take off the splash guard so you can get the inside of the panels. Thats where the rust most likly started from.

ive used Rust converter on other trucks and poured it on and just left it. It stopped it dead in its track.

I dont want take my paint off on the outside, as its only bubbles that are visible.. no holes yet. Will the converter cause holes and/or take paint off? How bout the linseed oil?

no the converter wont take off paint. Just wipe it off with a wet rag.
