HUNTER'S 1978 GMC C15 SIERRA BUILD THREAD
Now, I'm not sure just how well this encapsulator works but I figured a little bit is better than nothing. While that piece was cut out from the fender well I poked my phone up there with the camera and it was scaley scaley! I put a big leather glove on and went at it the best I could with a cheap wire brush and then stuck this can in there with a nozzle. It did a pretty good job at coating everything.
For some reason I didn't take a photo of the inside of the bedside, maybe because it was wet. In my last photo you can see it got all the way up inside of the bedrails as it oozed out from the holes previous owners drilled and the ones for my nice rails.
