Nice truck, and good color combo.

Re: 1990 GMC Sierra extended cab

Haven't done a whole lot to the truck in the past few week, several days of 100 degree plus heat index but I did get a battery tray ordered.

Today I started getting ready to pull the right inner fender shield to check out how much was damage was done from leaking battery acid. Before I could pull the inner shield I had to unbolt the running board on that side and pull it back far enough to get to the bolt so I decided to just take it completely off the see what the truck would look like without it. While pulling stuff just went on and took the broken bug shield off to, now just need to clean up that area and pull the bracket for the running boards. Will try and get inner shield off before days end.

Finally got the inner shield off and it didn't look to bad, a little cleaning up, some rust treatment and repair the hole that rusted through and it should be good to go. The next step is to check out the core support in that area.

I got the core support out yesterday and it didn't look near as bad as I thought it did after checking the cost of getting one shipped, more than cost of the core support itself. The only bad spot is under the battery tray area, anyway will start cleaning it up to see how bad the rust really is.

Re: 1990 GMC Sierra extended cab

I pulled out the usual, wire brush, sandpaper and my Harbor Freight air needle scaler. It cleaned up fairly well considering and after that gave it a good treatment of rust converter and let it set for a day or two. That last photo is after the rust converter has sit for a while. After that will make a card board template of that area and see how it goes.
