Evercoat Feather Fill G2 Premium Polyester Primer Surfacer for Fiberglass, SMC & More - 32 Fl Oz

For filling layer lines and finishing 3D print projects this is an absolutely amazing product. Spraying this requires a little bit of investment in tooling but it is an absolutely revolutionary experience compared to rattle can spray primer.

Along with the heavier Slick Sand this is the best primer I’ve ever used, if it’s time saving you are looking for? No other product comes close. These primers can fill the heaviest scratches 36 grit no problem, all those hours you spend taking those scratches down is reduced to the drying time with this amazing product. I use it for covering raw fiberglass,holes, pits, but have used it on wood and rusted steel, all reduced down to a flat, easily sandable surface.Spray on light at first, low pressure, let it build, then you can go really thick, sands a dream, I can get a glassy finish on it.No other primer is more reliable.

I’ve been doing fiberglass work for over forty years and used this a long time ago but switched to pcl brand. Bought this and I forgot how good it is. It fills great and sands easy

This is a known good reliable product.

My preference for primer/filler under either acrylic or Urethane automotive paint. It does not lift, fisheye, or run easily (must have proper substrate prep like all primers). It dries fast and sands easily. Sanding is only needed for dust nibs or if the sprayed primer has to sit longer than a few days. I still use my old Sharpe 75 LVHP guns. I truly dislike LPHV guns and do not experience overspray or air clouding with my old guns and this product.

great product and good service

Did not even put hardener in, can was sealed/taped. Opened and put into filter just to find half the can was basically putty. 2 quarts totally useless.

gos on thick. great for block sanding
