1981 CJ7 Restoration - 2019.04.27

It's been 4 months since I've done anything with the Jeep and I've been agonizing over how to get the frame and body parts stripped of old paint and rust. The thought of wire wheeling it with an angle grinder just makes me cringe since it is a very time-consuming and labor-intensive job that may take me weeks or months to complete.

Friends of mine have been saying that I should look into mobile media blasting companies, so I did. I found this outfit called Green Clean who are based in Stafford, VA and they were willing to come to my house to do some blasting work.

To give you an idea of what all needed to be done, the following are the main pieces and their pre-blasting condition.

Stripped frame, body components and other hardware.

Just prepping the frame was quite an undertaking. After 12 years of sitting in an outdoor tent, mice had made every part of the Jeep their home. I had to use an air compressor and vacuum cleaner to get all the crap inside the frame rails out. I'd blow air through the frame holes from one end to the other and see how much I could get to fall out of the holes. This took quite a lot of time, so I decided to back this up with a vacuum cleaner with a small hose attached to it to suck stuff out. Much of the debris were hickory nut shells, so I had to fish them out with needle-nosed pliers at times.

The frame cleaning setup.

The photo below is just what fell out of the frame. The photo doesn't do it justice since the dirt was at least a 1/2" high, and there were so many nut shells.

Some of the crap that had accumulated inside the frame rails.

The guys from Green Clean were great. They are a small business who uses glass bead media from recycled glass to "sand blast" whatever it is that you need to have stripped. It's environmentally safe, won't cause silicosis, like actual sand. It's also low heat, and if you have very sensitive pieces to blast, they can add water to "vapor blast" your parts, but it's rarely necessary since the glass bead media doesn't generate that much heat. Also, if you wet blast parts, if makes for an incredible amount of clean up since you have to get the wet glass media out of everything that was blasted. Luckily, everything I had done was just done dry.

The down side to dry blasting is the amount of dust that is generated. I parked my car on the street which is 100 yards away, and it was covered with a thin layer of glass dust by the end of the operation. Everyone in the area wore eye protection and respirators.

End results were excellent. I think what Green Clean did would've taken me 6 months to accomplish.

What a transformation! Saved me months of dreadful work.
