CP_70_SS396 Oct 6th, 00, 4:00 PM I'm assuming people mean baking soda when they mention soda blasting. My question is, Can this method be used on the hard plastic dash carrier ? I want to strip this part completely clean without damaging it of course. Easy off and pressure washer didn't quite take off all the black. Thanks. ------------------ Chris TC Member #631 micky69396 Oct 6th, 00, 4:39 PM If you have a good media blaster, some types of plastic media can also be used for this without damage. ------------------ Micky Hale Restorations 69 L-89 Chevelle 68 Biscayne 427/425 34 Plymouth Drag Car ACES #134 www.mickyhale.com CP_70_SS396 Oct 6th, 00, 5:40 PM Micky, I would be using a 40lb pressurized blaster. I don't have a cabinet of any type. Would this type of blaster be acceptable with baking soda ? ------------------ Chris TC Member #631 micky69396 Oct 6th, 00, 7:26 PM I dont know, I imagine it would but I am not in that business and I wont tell you to go for it. Somebody here might know something on that better than I would. CP_70_SS396 Oct 6th, 00, 8:05 PM Guess I'll get a 10lb sack of baking soda and give it a whirl on a scrap piece of plastic and see what happens. If anything it may just prove to be interesting. Thanks for taking time to respond. http://www.chevelles.com/forum/smile.gif ------------------ Chris TC Member #631 MARTINSR Oct 6th, 00, 11:48 PM DON'T USE SODA! I have seen soda cause very bad adhesion problems. Use plastic media or a urethane paint striper designed for striping paint off of urethane bumpers. NAPA has one in an aerosol, it's # 7230. ------------------ 1965 Buick Gran Sport Convertible 1965 Buick Skylark H/T CP_70_SS396 Oct 7th, 00, 12:12 AM MARTINSR, This is something I'm not familiar with of course. What exactly is plastic media ? Where is this obtained from ? Will the NAPA #7230 remove everything as well ? ------------------ Chris TC Member #631 MARTINSR Oct 7th, 00, 9:08 AM The 7230 is for striping paint off fiberglass and plastic bumpers. I would use it as a last resort though. Why can't you sand it off, or almost off? I don't know where you get the plastic media,(little plastic balls, almost the size of large sand) I just know that it works great and there are many shops around the San Fran bay area that strip car this way. It does no harm to the metal or glass, just removes the paint. ------------------ 1965 Buick Gran Sport Convertible 1965 Buick Skylark H/T CP_70_SS396 Oct 7th, 00, 11:29 AM This would be for a dash carrier which has a simulated grain surface. Sanding would ruin that. I may see if I can find the plastic media. Someone has to have it. There's a solution I'm sure. http://www.chevelles.com/forum/smile.gif ------------------ Chris TC Member #631 micky69396 Oct 7th, 00, 6:27 PM If you have a Hemmings try TIP in Ohio, they have all kinds of media, and may be able to help your on which may be best for you ordeal. Walnut shells may work also. Stay away from chemicals if possible. MartinSr, I wouldnt have thought about a adhesion problem with the soda. What does the use of soda do to the plastic to cause a problem? Just curious? Good info.

I realize that the point is now moot, but it seems best to spray over the factory paint if thats all that is on it. Good luck with it. ------------------ Rainer Seitz Vancouver, WA Team Chevelle Gold #50 ACES #3784 '68 SS396 '70 LS3 400 Malibu '70 Malibu convertible 350/300hp rseitz@chevelles.com CP_70_SS396 Oct 8th, 00, 12:27 AM Rainer, There's a silver color showing. Like the shiny side of aluminum foil. Plus there's still alot of black paint left. I assume the shiny stuff is the bottom layer. I thought I had read that somewhere here. I just wanted to get rid of all the black stuff so the grain wouldn't be fuller in some spots more than others when sprayed with new paint. Plus if I spray it and it turns out kinda crappy, I'd like to be able to blast it off. ------------------ Chris TC Member #631 MARTINSR Oct 8th, 00, 10:19 AM I have seen the Soda blast cause a problem on metal, and I just STAY AWAY from it. It was a complete paint job on a 1955 Chevy, the paint just peeled off...right down to the metal. It was stripped, sanded and etch primed...same thing. The Soda was somehow impregnated into the metal! It is VERY fine, and that is the nearest thing we could tell happened. ------------------ 1965 Buick Gran Sport Convertible 1965 Buick Skylark H/T | ||
