shaft brush?

[HUNTHARD]

I was looking over a recent survey and it stated there was no room on the shaft for a zinc. It Suggested using a shaft brush inside to allow for bonding. Does anyone have a picture of this and how much they cost to install?
Thanks.

thanks, El mar. i looked it up but thought there was more too it.
nice to know some things are easy fixes.
Okay next question on a fiberglass tank with a bronze barb fill does the fill have to be grounded even though the tank is fiberglass?

No sea water contact= no bonding.

jwalka thanks for clearing that up for me.
one more question what should you use to bung the screw heads on the spray rails?
Is there a specific putty or sealant used for this particular application?

I use bung material (pvc rod the right color) and some pvc cement (clear)

Thanks, First team. So you push the pvc on top of the head with the cement on it, then cut the small push rod with pvc cement on it flush with the pray rail then just whip clean before it dries? Or something like that? HAHA.

I cut my bung material into 4-6" lengths, ran them through a pencil sharpener in my pocket for a little bit to soften the edge, dip em and tap them in, have about 10 or 12 of the lengths, just go down the line, when you get to the end go back and start trimming them off with a hacksaw blade. Then you just twist the ends in the sharpener and dip and tap them again. Goes pretty quick once you get the motion going.
