I found this ''plastic'' tape @ work. It is a rigid poly like material that is still bendable. I have used it as a shim for magnets and am going to try using it stacked under osss magnets as a spacer for installing them in magnatraction chassis. The tape is sandable not sure if paint would adhere to it.Hope the pics can give an idea of thickness. Just thought it was neat and I'd share
I have discovered that when this tape is applied to the back side of tyco 440x2 motor magnets they fit real nice in the original g-plus chassis, along with the afx blazing brake chassis which is basicially the same without the hard to find brush barrel/pick-up shoe holding tab.The blazing brake chassis also has a "snap in" rear axle set up. I'm gonna try out this set up at Smokey Mountain. The Tyco magnets seem to add a lot of zip to the stock g-plus arm.
