I’m sure I’ll think of something.

There is a silicone paint called Psycho paint for platinum cured silicone. I used to use a very thin RTV silicone for waterproofing circuit boards. I think you could make a paint out of that if you added the right kind of pigment to it.

Jane truly is lovely.

Sometimes you need something pretty firm (leveling out the bottom of something you don’t want rocking around frex) and sometimes you want something a little squishy (those various mended handgrips, earbud plug covers, and etc would be more comfortable to use slightly squishy than extra-hard).

Although after that paragraph, I’m sure everyone’s thinking about Angstrom’s “Dildo kit” comment ;)

Dildos aside, I’m wondering what sort of paint (if any) would adhere to this. It would have to be pretty elastic to survive on the flexible surface. Is there such a thing as silicon-rubber paint? That would solve the adherance and flexibility problems right there, if it isn’t an entirely fictional product.

Is it food grade. And what sort of solvents are emitted during curing. Do you want your kids’ noses close to it in still air, while they make colorful tentacles, dinosaurs, flowers and nail extensions?

How well does it stick to ceramics, metal, plastics etc. If you make a handle out of it, can you rely on it not coming unstuck? Can it be sanded?

Like #7, If these questions are dealt with on the Sugru site, they remained hidden from me. Some of these questions are asked in comments on the Sugur blog, but no answers. But I’d love to play with it myself. Looks like fun.

My usual go-to is Atlas plumber’s epoxy. It sticks well if you mix a touch of water into it while kneading. Sets hard and can be sanded. Toxicity unknown. Thanks to the other Boingboing commenters for suggesting their favorite sticky putties. Valuable knowledge.

Melts at 60 degrees C, sets to super tough slightly flexible plastic similar to solid polyurethane.

You can do anything with it you can do with cast plastic, cogs for example.

The bones of this robot are made out of it:

1) Is it food safe? I mean, if I repair a mug, is it safe to drink out of the mug?

2) Does it shrink (or grow) as it hardens?

If the answers are “yes” and “only a little” then ‘useful’ is hardly the word to describe this product. ‘life-changing’ might be better, at least in my case…

Having a choice between a harder or softer final product for example. Or a version that was more of a liquid, which would allow painting or dipping as application methods…

I would guess since it’s probably just precisely that with a little plasticizer in it, it will probably shrink *mildly* in size as its used and have a larger temperature range over which its useful. Probably also decreases the melting temperature though, so don’t put anything like this in the oven.

• sugru isn’t suitable for use in direct or prolonged contact with food.

Darnit.

Still could be a life-changer for a lot of people if it doesn’t change size much when it dries — in other words, if it can be formed using a mould.
