That's what I've been using for Saltwater plastic. It's great plastic, very tough/resilient, but it gets a little oily after it cures...and I mean my kind of curing (4-6 weeks).
Because of the oily aspect, I'm looking at MF Floating Original, either Medium or 464 for my Saltwater plastic. I'd use Bounce/SuperFloat BUT that plastic CAN NOT laminate. I don't shoot laminates but I do dip quite a bit so I need the layers of the dip/dips to adhere so I can't use Bounce for that.
MF Easy Stretch is killer, it's just oily after it cures.
I use MF Original Floating Super Soft (it's just Soft) for the bulk of my soft plastics, and MF Bounce Soft for most plastics I use on top. I like that Bounce...!...it just doesn't stick to itself, even with a Twinject (report I received). If You shoot Bounce into a mold, then open the mold, You'll see how it almost jumps off of everything.
Bounce is an awesome plastic if You're not shooting/pouring laminates or dipping.
I'm still undecided if my next hit of plastisol will be Medium or 464.
