There's been a bit of chatter over the last couple of days about positive results achieved with a needle scaler tool for the removal of tar-pad sound dampener from floor panels, and even undercoating from the car's underside surfaces. That's great information and looks the a a heck of ot more convenient than dry ice, CO2 blasting, scrapers, blow torches and heat guns! However, I'm interested in hearing about the use of this tool for cleaning and conditioning aluminum castings. I'm thinking specifically of the Z's valve cover and SU carb bells. In both cases, the parts don't lend themselves to blast cabinet treatment (because of the size of the part size in one case, and because of the risk of media-particle part contamination in the other). In addition, the end result from blasting these parts isn't necessarily a correct look -- to my eye, anyway (it's a little too bright and porous-looking). I think I recall someone saying that a needle scaler delivers a more OE look for these types of castings (a smooth, 'hardened' surface look, kind of like shot-peening at a miniature scale). Has anyone tried this? Any before/after (or even just 'after') pix to share?
