Product Code: B506

This is a primer designed to fill in scratches, uneven surfaces, bubbles formed during modifications, and gaps in parts, eliminating imperfections in the substrate. It is especially ideal for scratch repair and can be used as a liquid putty.
The 500 version has the coarsest granules and is probably best suited for gap filling & repair. 
It is grey in color, and it is available in both bottled and spray format.
