Since not many kits out there holds the status of "absolute perfect fit", we face sanding issues on most of our builds. There's plenty available tools, sandpapers, sticks and blocks dedicated for this stage of model assembly. And we want to pass it quickly and easily, which is however in opposite with keeping all moulded details and surrounding surfaces intact.
The option we often choose is use of sandpaper with higher grit number (Super&Ultra fine microgrits). But that is slowing us down, especially when heavy sanding is needed due to very bad fit of plastic parts.
Friend of mine, fellow modeller, had recommended sandpaper which whilst having significantly low grit number is causing only reasonable damage to plastic. There is unfortunately no Manufacturer name printed, all it says is SUPER EasyCUT WET + DRY ELECTRO COATED LATEX cwt ALOXYDE.
