filling palette foam

[Tamiya]

had a wierd lumpy grip come my way, so i dissected it.
Under the OG & leather OEM grip... some owner had bright idea of
gluing the grip with silicone sealant (yeah the bathroom kind)
& possibly filling up some holes in foam palette

now that all the gunk is removed... what's best material for filling the big holes?

i'm thinking putty or drywall spak is probably too dense & hard

how about space-filler foam from a spraycan, will that go brittle under grip?

[must.... resist.... suggesting... silicone sealant...]

The main requirement seems to be something that dries with the same volume it had when wet, or else something that can be easily trimmed if it dries with greater volume. The space-filler foam can be easily trimmed to make a flat surface, and its brittleness shouldn't matter if you're just filling in a couple of holes that will be surrounded by handle foam and covered by grip and overgrip.

I believe putty comes in different densities, and a little weight added underneath the hand shouldn't have noticeable effects on playability.

You might also go to a Michael's, or other hobby store, and get their advice on the matter. Good luck!

Epoxy resin - says my industrial design background...

Actually, ignore.

I agree, plus adding micro-balloon to create a structural light weight filler.

I think an epoxy approach might melt the existing foam upon contact. ?
Wood putty/filler is a thought or perhaps a caulk compound other than silicone based?

I've repaired chunks of missing pallet foam with the epoxy/balloon mix and it didn't affect the original pallet. You'd think the heat generated may melt the foam (it does get quite hot), but it didn't. With that said, there are cheaper alternatives that can get the job done.

What would the cheaper alternatives be?

How about small pieces of a Gamma grip buildup sheet?

Alternatives mentioned before, ie. putty, silicon caulk, etc. They'll weigh more, but shouldn't matter at the handle.

was aiming for some 5min epoxy + microballoons as used in balsa RC frame building,
but LHS didn't have any in stock damned lazy modern RCers
are all buying ARTF & RTFs now, too lazy to build themselves

Meanwhile have sealed the cavity with superglue. Didn't melt the foam.
