Evercoat® Featherfill G2 Gray Gallon is rated 4.5 out of 5 by 4.
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.

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.

Asked by: Tony Trevizo
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.
