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

Rated 5 out of 5 by from Great Product I sprayed this product on my 76 Vette a couple days ago and sanded on the finished product today and am ready to give my review. Excellent if you do the below Use a big tip, 1.8 minimum I live in Houston, G2 does not like to be in hot environments once activated unless reduced, I wasted a quart learning this, and had to switch to my finish gun after changing its tip due to primer gun being plugged up. Wont take much reducer, but you'll be thankful you did, I had no issues after that. It has excellent fill qualities for small stuff and the color makes it easy to find spots that need a little more work. Sandability it excellent with 400 and it comes out like glass. Very happy with this product, will us again

Rated 5 out of 5 by from Featherfill info and best usage. To help out with what featherfill is, and is not, I hope this may help. Featherfill is really more of a sprayable body filler than a primer. It has a hardner more like fiberglass resin or body filler than a paint catalyst. When pushed, Featherfill can do wonders... You really could spray it over 36 grit and never see it come back, but stick to 80 greit finishing. When Featherfill is properly dry, it's done... it will not shrink months down the road or show sand scratches. However, it is a body filler, and one that does not like to be on bare metal. So finish off your body work, hit it with a good epoxy primer to seal it off, and then spray the feather fill. Use a big gun, seriously... a 2.5 will have you looking for more, don't even think about that junk 1.4 gun you have laying around, it's not going to work! Once dry, dry block with some nice foam Dura-Blocks with 180 and finish with 320. Follow this with a good 2k surfacer primer. Remember, body filler... not primer, you will want to finish it with a primer before paint.

Rated 5 out of 5 by from Featherfill G2 Gray Primer - Really Good Stuff! Good primer with high fill characteristics. Be sure and really stir up the container because there are a lot of solids on the bottom after the container has been on the shelf a while. Can be thinned with Acetone, which is the best to slow down the drying time. Add the Acetone if you are spraying in summer temperatures like we have here on Texas mornings (88 to 95 degrees F.) Use a 2.0 mm nozzle as a minimum, because this stuff is quite thick. Flows on very nicely when thinned. Use two coats to cover any body fillers. Dry sands (220 grit) without clogging the paper. One more coat, then 400 grit and then the topcoat. Very good product. Cleans up with Acetone.

Rated 4 out of 5 by from Good from what my dad tells me I bought this for my dad for fathers day. he kept asking me whether it was good or not so i did research to find out. I needed to find a good primer/filler for his project car. he's built a fiber glass body kit car etc. so he needed one that wouldn't dissolve fiber glass. I found out about G2 feather fill, heard good reviews and decided to give it a shot. After it arrived he was so excited to use it. but he never had the time. he eventually found time to apply it and when he came inside after the spray job he kept telling me how fantastic it was spraying. he said he applied a little thinner to it to make it easier to spray. but he wouldn't stop talking about it for the next 2 days. when he finally got the chance to sand the car he again came inside and continued raving about how well it sanded and how smooth it was after he finished. he asked me to buy another gallon for him but this time i made sure it came out of his pocket. Overall I have no experience with the product but it made my dad really happy so I think its a great product.

Rated 4 out of 5 by from Great stuff but be sure to have a 2.0-2.2 gun nozzle tip Stir, stir, stir! Make sure there are no lumps in this before shooting. My results were best with a 2.1mm spray gun nozzle. Anything smaller runs the risk of clogging the gun. Builds up low areas nicely. Relatively EZ sanding.

How long is too long to work on block sanding before sealing with epoxy? A few weeks to a month or more? I’m guessing humidity plays a factor? Unfortunately we experience humid and dry conditions, living in the Midwest. 

Asked by: Benny
So let’s say for the sake of argument, humidity is at 40%? Or the humidity is at 60%? What does the timeframe look like for those different levels?

I’m using Evercoat Feather Fill Polyester Primer. I have put one good coat on my car when had a issue with my gun. So to put a second coat on what would I need to do prior to doing this when it has been several hours since first coat was sprayed on.

Asked by: Wrtyman
You will need to scuff up the primer after 90 minutes. then apply your second coat.

Per below question which sealer would you recommend so I can get it on the way, my color has changed, I have y'alls feather fill and Pure White on the way now, then finishing with tropical sunset pearl and yalls high end clear.

Asked by: Lardog Houston
We recommend using our Epoxy primer reduced by 20% with Urethane reducer and applying this as your sealer coat. White Epoxy would be ideal in this scenario.

I am wanting to go with Chop Top Silver on my Vette, can it be sprayed over the feather fill once sanded, or should I add another step in between for best results on my base coat.

Asked by: Lardog Houston
It is always best to apply a sealer coat. here is why. Most likely you would either get a lightly ringed area around the filler or would get both the ring and pop marks as the paint would react to the filler. The biggest key to a perfect paint job is prep. With out proper prep ANY paint/ paint job would turn bad

Can I topcoat directly over Featherfill G2 with acrylic enamel? I seen folks saying you can topcoat with acrylic lacquer or urethane enamel but am wondering if it is the same for acrylic enamel.

Asked by: Brad
The Feather Fill will accept a lot of different top coats. We have not tested this product while using acrylic enamel. Best thing to do would be to try this on a small test panel, to see if there is any chemical reaction.
