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! |
