There are multiple application methods that can be used. For this particular application, I needed a flat-bladed screwdriver and a bit of lube (I used elbow grease).
After a moment or two to diagnose exactly what locations were rattling, all it took was several well placed turns of the screw driver, ample elbow grease applied (the screws were well rusted on the hose clamps the previous owner used previously) and my 1.5 remaining heat shields just came right off! no more rattle!
The website for
BrewGuyTim's Rattle-B-Gone® is forth-coming, as we're only in trial runs at this point, but it should be available at your neighborhood retailer (AutoZone, O'reilly, WalMart, etc) within the next millenia.
