    Default Evercoat Fiberfil G2 question

    I'm doing body work on an aluminum hood and planning on using Evercoat Fiberfil G2 on it. Do I need to prime the aluminum with 2K or can I spray the fill directly onto the aluminum? If I can put it on directly, what grit sandpaper prep should I use?

    Also have a question about applying the G2. I've never used this material so not sure about spray equipment. I'll be using a DeVilbiss gun with a 2.2MM tip. Should this work?

    Thanks for the help

    Sorry, I canít speak about aluminum with authority but I think you can spray it. Check the technical data sheet from Evercoatís site for the real information. I use a 2.2 tip on my primer gun for spraying G2. Itís one of my favorites. Be in a hurry when you spray and get the gun empty and clean it very soon and very well. Itís hard to deal with once it starts setting up but itís a very nice filler and easy to apply.

    Yes, it MUST be epoxy primered prior to shooting the Evercoat G2 FF over aluminum or it will lift. A 2.2 tip is perfect for this application WITHOUT the 10% acetone reduction (I would still reduce with 2% acetone for that extreme smooth shot). A good epoxy primer can be expensive and adds an extra step to bare metals, this is one of the reason I switched to Evercoat Optrex 4:1 as it alleviates the need for first coat epoxy primer and spray filler (nice dollar and time savings). Feather Fill still has it's place down the road and I continue to use it, just not for initial shot. Look up the TDS for the Evercoat Optex 4:1 primer/filler, it is a nice change. If you go this route learn to do an initial surface break as this product as is like sanding concrete.
