Default Fuel Proofing arfs firewall?

Have a few arfs here Hangar9 and Great Planes. Have been in the habit of doping the firewalls. Was unsure if they were allready coated. However since the dope didn't stick that great im sure they must be allready done. Putting together a hangar9 alpha right now and have allready locktighted the motor mount in. trying to decide weather or not to remove the mount or not and do the fire wall. Others here do extra fuel proofing to your arfs? Don't recall instructions calling for any,(thinking, gona double check). must have to do dowls for rubber bands or they would get soaked.

I sure as heck reinforce any ARF firewall I have, usually by adding a layer of fiberglass inside the fuse overlapping the joint between fuse and firewall, and then coating the outside of the firewall with finishing resin, which fuelprrofs it, too.

For firewalls I use resin, thinned 10% by volume for fuel proofing.
