If I use rebound 25, or a similar platinum for a 'paint coat' can I then backfill the mold box with a cheaper silicone?
Anyone ever tried this?
I get great results with rebound 25 on some of my parts, but I hate doing box molds with that expensive stuff, and I dont want to degauss cheaper/other stuff.
Anyone?
The mold im working on will require a pretty thick box/mold because its going to be foam filled.
nope... mixing types doesn't work so well. i tried mixing rebound and oomoo and they didn't bond at all.
why are you using rebound for a box mold and not something like oomoo? you don't need to have a degassing chamber for that stuff, and it's a lot cheaper than the rebound.
I was using what I had. MOstly for small box parts, like my earpieces. If you say the oomoo si good, ill buy some of that:)
Out of curiousity one of the primers/paints I use the rebound doesnt like, it doesnt cure on it. What would you suggest to seal my plugs/parts with before molding them?
well, i didn't say the oomoo was *good*, just that it was cheaper ;)Quote:

you'll have better luck using materials that are formulated for what you're doing. a pourable silicone will capture details when you pour it on more easily than a brushable.
and besides, it's fun having a ton of blue and yellow buckets around!
