Has anyone tried this method of removing the decades' residue from our fossils? The usual method appears to be a common pressure washer with an attachment that siphons up the sand near the nozzle and squirts it with the water. Now normally, sand and water and sandblasting are a no-no; I just bought a pressurised little unit and it is worthless unless you can keep every drop of moisture out of it (you can't)and for every ten minutes of blasting, spend thirty cleaning up and fifteen cursing and banging the nozzle around in frustration. JC Whitney sell a cheap little unit that seems to merely consist of a gun, a water pick-up,a pressure line and a siphon tube which you stick into a bucket of abrasive. Has anyone tried this or something similar? At less than 40 dollars it might be worth a try. I just finished gutting my cab and some form of sandblasting would have been great to get into all the nooks and crannies. I did the best I could by wirebrushing and squirted some kind of tough green epoxy paint all over the inside which looked a little too much like a certain famous agricultural green to me until it dried. I will get a bumper sticker; "No, this is not a John Deere..."
Hello , I've never yet tried the water sandblasting deal. I've sand blasted and even herd about baking soda and walnut shell blasting. Reguardless , when all blasting is done make sure to also sand the areas down and as soon as humanly possible put down a reputable paint manufactures "acid etch" primer first. Corrosion starts the second bare metal is exposed . Good luck , Chris
