I know some of you folks will have some advise for me on this subject...
I need answers to several questions regarding media blasting... 1. Is the 'Pressure Pot" Blast System significantly superior to the gravity fed system? I can get either one at Harbor Freight (and prolly other places) for about $50.00 difference, which is trivial, IF the Pressure Pot system really works better... 2. I can get Aluminum Oxide media for $40 per 25lb box... how much surface area will this cover, assuming I am removing the factory paint down to bare sheetmetal? 5 square feet? 10 square feet? More? For an easy example, will 25 lbs strip the hood of a 914? Or maybe the hood and trunk (top surface only)? 3. I can get crushed walnut shells for about $20.00 per box, but i assume they are much less effective? How much less? Will it take twice as much in walnut shells vs. aluminum oxide? 4. Luckily, I only need to strip the exterior, as the interior is in fantastic shape, and I am repainting to original color. What is the best material to use to mask areas that I don't want to get "accidentally" blasted? Heavy duct tape? Multiple layers of heavy plastic sheeting? 5. Will Aluminum Oxide risk warping of the sheet metal due to heating? I understand walnut shells won't warp panels? True or not? If they are only marginally less effective, and half the price, I guess I will go with the walnut shells? Prolly more, but that is all I can think of right now! Thanks folks! |

I'm thinking of getting one or two of those disposable white "paint suits", and a full face respirator, and wait until the temps are somewhat cooler. My shop is large, and I can hang plastic curtains to contain the debris. In fact, the ceiling is already covered with plastic, so just need to do the side containment.
Very good tips! Should help out a LOT when i finally get into throwing stuff at the car! I noticed the instruction book on the Pressure Pot I am thinking of buying specifically called for using the 45 degree angle of approach, so that must be a very key point. And just like a paint gun, Keep It Moving!!! All makes sense! |
