This is a new product made by Evercoat. The products is used to glaze over your final body filler work to fill and seal any pin holes that may be left behind after sanding. To use the 440 Final Prep Micro-Pinhole Eliminator, just use the applicator that comes with the kit to rub the product over the surface.
If you have an issue with pinholes after sanding, this may be a product worth considering. By fill the pinholes, you will reduce the use of additional putty glaze and primer surfacer needed to complete the repair and have it ready for paint.
