I’m writing this covered in baking soda, waiting for the rest of the family to finish showering so that I can wash it off, and feeling pretty good about things. On Sunday afternoon I bought a $70 Harbor Freight sandblasting kit and a $40 bag of blasting media so that I could continue cleaning off the windshields. It took about 3/4 of a beer to get everything assembled; the directions are mostly pictures and designed by drunks with limited understanding of a 30-year-old Xerox machine. Using the pictures in the instructions, the picture on the cover of the box and a lot of common sense I was able to figure out how to put everything together, and after masking up I dumped some media in the tank and had at it. Once I dialed the flow coming from the bottom of the tank in, I was able to get the maximum effect with the minimum amount of media.

Soda doesn’t do much for rust but it sure takes the paint off quickly and well. I put about 1/2 the bag through the tank and worked over both windshields, focusing on places around obvious rust and scratches. I guess I’ll have to switch over to actual sand or maybe walnut shells to get the heavy rust off. I did find that the second windshield has one pinhole area on the top flat surface, which I hadn’t noticed before.

When I was done I realized the entire driveway was covered in blasting media, and I freaked out a little bit. But then I hit it with the hose and it all melted away. Clearly I need to build a cheapo plastic blasting cabinet so that I can reclaim the media and use it again, especially when I’m blasting small parts.
