Re: 71 K20 Idaho Edition

Finally got around to cutting out the pin holed area a day or so ago. After removing the piece it took a bit to get all of the tar paper off and as much of the tar that was stuck to the bottom layer of metal. What I saw did not leave in a very good mood thinking that the roof might be shot or that I would at least need to cut the whole top skin off and order a repop skin and replace.

Went back inside and started doing research on buying that part and what was the best way to tackle the project. After a day or so of reading a few articles and forum post I remembered that someone was taking about they thought their roof was toast also when they opened it up. Then when they got further into the cleanup stage found that the lower layer of metal that looked rusted was actually the tar with surface rust from upper layer stuck to it. So I went out in to the garage and sprayed a large section Rustoleum rust dissolver on the left side and let it sit over night. When I came back out the next morning it did nothing to the area, so I grabbed an old chisel that I use to scrap old gaskets and such and started to scrape the area and found that after the tar was taken off the metal underneath was as good as new.

Well that made me happy so I will proceed with repairing the area and treating the metal top and bottom best I can.
