Evercoat® Featherfill G2 Gray Gallon

Product Overview:


Feather Fill G2 is a high solids polyester primer surfacer that is VOC compliant. It is specially designed to hold down body repair areas and provide an excellent foundation for any paint system. It has excellent adhesion to fiberglass, SMC, body filler and wood surfaces.

  • High Build Formula with minimal texture on surface
  • Excellent adhesion to fiberglass, SMC and wood
  • Fast Dry-to-Sand time reduces cycle time
  • Waterborne compatible and VOC compliant
  • MEKP Activator included

Many shops commonly apply self-etching primer to bare metal surfaces. But most polyester fillers and epoxy primers should not be applied directly over self-etching primers. So what do you apply when you need additional filling? Feather Fill G2 is the answer.


Rigid Plastics
Body Filler or Putty
Epoxy Primer
Self-Etch Primer (extends dry-to-sand time)

NOTE: All bare metal areas larger than one inch in diameter must be treated with a high quality self-etch or epoxy primer.

- Shake and stir thoroughly before mixing
- Add one tube (.75 fl. oz.) liquid hardener to one quart of Feather Fill or 2% by weight and mix thoroughly
- Pot Life is 35 minutes @ 75°F (24°C)
- Do not leave product in the spray gun for longer than 45 minutes

- Use a primer gun with a 1.7 to 2.2 fluid nozzle/air cap (Spray at paint gun manufacturer’s recommended air pressure)
- Apply 2-3 medium wet coats allowing 5-10 minutes flash time between coats

- Ready to sand in 75-90 minutes depending on film build
- Applying over self-etch primer could add 4-6 hours to the dry time
- Once dry sand Feather Fill with 400-600 grit sandpaper prior to next step

I sprayed the G2 about 4 days ago. Mixed as per the TDS. It’s sandable, but gums up the 80 grit quickly. It seems cured but has me concerned. Should I strip it or DA with 80 and spray it again. Or should I put a radiant heater on it?

Asked by: DanDrak
It sounds like this primer has not fully cured yet. Please keep in mind the recommended curing times are relatively accurate when mixed accordingly and at a 70F ambient temperature. Lower temperatures will increase the full cure time.

i sprayed and block sanded this last fall then sprayed the second set of coats last fall and block sanded this spring. I am ready to spray the 2k primer surfacer now as a sealer but do I need to worry about moisture having been absorbed through the air?

Asked by: johnK
Unfortunately polyester primers will absorb moisture through the air. The only option now would be to remove the primer and start over to ensure good product. In the future we would recommend sealing up the Poly primer with our Epoxy if you know it will be sitting for a long time.

What would be the best sealer over FeatherFill G2? Urethane or Epoxy? I have Eastwood Epoxy under the FeatherFill.

Asked by: Don6952
Our Epoxy primer makes an excellent sealer when reduced with urethane reducer.

I shot the Feather Fill over Eastwood Epoxy Primer and after block sanding i noticed a few small low spots. Can Contour Body Filler be applied on top of sanded feather fill or should I sand those spots back down to the Epoxy Primer?

Asked by: Don6952
We generally do not recommend applying body filler over the feather fill. If the areas are very small you could certainly just apply 2-3 more coats of feather fill or if you need more sand back to epoxy to apply your body filler.

I have a bass boat with some spider cracks in the Gel coat. Can I send them down and go over it with featherfill And then Seal it and Paint it

Asked by: Wisconsin bound
All of our testing of any products we sell is centered around the automotive field. We have never tested on boats for long term durability. With that said though it would be very similar to a fiberglass bodied car and should work perfectly.

How long after spraying epoxy primer do you have to wait to spray feather fill polyester. I sprayed epoxy and waited half hour and then sprayed polyester and a week later when I sand it it gums paper up and the epoxy is like chewing gum

Asked by: Wrldlwst
If the temperatures are below 70F and the epoxy was sprayed on heavy it is quite possible for it to still be soft after a week as it is a slow curing product for strength.

Can this be wet sanded

Asked by: Wrldlwst
Since this is a polyester product we do not recommend wet sanding. Dry sanding is the best method.

Do you put the can on a shaker before you ship it, or do you get it with all the solids stuck on the bottom of the can?

Asked by: FXDC
These cans do not get placed on a shaker prior to shipping. You will definitely want to thoroughly stir prior to using.

What is the mixing ratio for the primer? It's been on the shelf for a few months and the label is torn. Thank you.

The ratio is 100:2. Featherfill activator comes in small .75 ml tubes. You only need one tube per quart.

Can this be applied over eastwood epoxy primer? also can 2k primer-sealer be applied over this before base coat?

Asked by: isaacjh
This product can certainly be applied over top of our Epoxy primer. Then the 2k Urethane primer will be perfect to finish it off prior to paint.

I build radio control model airplanes. I lay down fiberglass over balsa wood with finishing resin. I will use a 2 part epoxy paint on the model. Can I use your Feather Fill Primer as my fill for the fiberglass cloth and primer base for the epoxy paint?
