just found this over at sparkfun and it looks like it could find some uses in the mp3car community>
would be interested in anyone's feedback if they've tried it before
dude this thing seems pretty awesome!! the only problem seems to be its melting point (60 celcius)... also i wonder how it reacts at sanding?? (etc, can u make it smooth :P). yes some feedback would be cool (in this crap hole i leave i wont ever find it :P)
yeah, it says it has properties similar to nylon. i dont know how well it can be sanded but says it can be drilled.
i saw this a couple weeks ago at sparkfun--when they first posted it in the new products video, and ever since have been trying to figure out how to use it-- it would be the perfect material to allow me to rebuild my sail panels(to delete a useless set of factory tweeter holes), though i also have fears of permanently installing it and it drooping on a hot day...
SparkFun's website says this stuff melts at about 60°C (140°F). I suspect the inside of your car can get over that on a sunny day in the summer.
Just a thought. Not trying to be a wet towel.
I have this stuff (bought it on Amazon, but if I knew SparkFun had it, I'd have bought it from them...I love those guys).
It's pretty warm when you get it out of the pot but cools off quickly and is hard as S*** when it finally cools all the way.
I used some Diagonal Cutters to trim it after I molded my piece and it's difficult but not too bad. I didn't sand it. I'm treating it like a tool, not a building material, since it's re-meltable (I'm coining that term!).
I laid some blue tape down on my center console, smashed the polymorph onto it, let it cool, then put blue tape on the bottom of the polymorph mold.....THEN....I used some more polymorph to mold to the bottom of the original mold, effectively re-creating my original piece. I did all this for 2 reasons:
I wanted to make my piece (holder/mount of my Connexion 3D Navigator) out of fiberglass but I really don't like doing glass in the vehicle... I'll do it if I have to but really don't like to.
Also, it's starting to get cold outside and I didn't feel like spending hours out in the parking lot laying out tons of tape/plastic/fiberglass and resin/etc with cold hands and then waiting for extra long for it to harden in the cold when I could glass it inside, in the basement (ventilated through my dryer outlet) where it's warm and I have room to work and am not too worried about getting resin on the seats.
I'll post some pics in my build log once I get around to it (have the pics and most of the write-up, but all of my spare time goes towards overbuilding this friggin' build at the moment).
Shizzle has the right idea. While this stuff isn't a suitable solution for custom parts, you can make a silicone mold of the polymorph piece and pour in a chemically-melted plastic to form a permanent part.

Agreed. You could probably get by though with using it to make some smaller parts like knobs or small component cases (I saw someone asking for a F.B. case the other day) (it is very hard when it cools, like ABS but I don't know of the durability of it... no reason to doubt it since it feels solid but I just don't know what it can take).
One of the cool things is that you can make a piece then heat up a section with something like a lighter/torch and then attach another piece to that heated section.
*Note that if you do what I did and use this as a mold, make sure you're real liberal with the tape. The Fiberglass Resin really likes to stick to this stuff and you may end up having to cut portions of the polymorph off to get a "clean" piece to re-heat for future use.
i have used this stuff only made by a different company. the stuff used was called shapelock and you an drill it but it doesnt do to well with heat at all...i used it to make a custom LED domelight insert and in the summer in a hot car it melts pretty quickly...now that could have been due to the fact that it was pretty much right up against my roof. It is some useful stuff though.
