I have it and use it. Its great for one offs, and not bad for limited pours.
Just keep the microwave handy.
melt to use it, when your done remelt it and back into the tub for next time.
Not bad stuff really, I do mostly driver figures etc with it.

...thought Dan was talking about me...

Two questions:

Can mold release be used in order to make a 2-part mold?

Can resin release be used with this? I'm concerned that melting it back down might mess with it.

I'd like to try this if it does.

Just a quick question !
Would this container be enough product to do a
mold of a 32 scale diecast truck,if i keep the mold box as small as possible??
thanks ecr :character-oldtimer:

[Dangermouse]

awesome

ecr there is a math problem for you - what size box would you need for you truck?

working out the volume - I don't work in ounces - 40 ounces is about a litre - a litre will fill a box 10cmx10cmx10cm - which is 4inch square so I am guessing one tub won't be enough :)

David,

I was wondering that too.

David, I haven't used release agents with it as it may contaminate the product.
I pour resin parts and figures with it, then cut the product as carefully as possible to remove the buck figures. If I was lucky, I can use the mold a few more times. If not, just break it up into chunks and put it back into, the container, re heat and it melts back to original .
Next use,,,, heat it to a liquid again and pour over the next mold. Once hardened , remove the mold and do your pours with resin.
it is designed to benused over and over, but gets hot so be careful not to burn your self.
sorry I cant help with quantities, but I bought 2 of the smaller containers for small one offs .

BTW, It is true of me and David but don't tell him.

informative video.. I assume the time it would take to vac the rubber would probably cut down the work time. Not interested here, cutting corners is not the way to go and get good smooth molds. I`ll stay with what works !!

[ddyke]

Sometimes I want to make a rough copy of something so I can modify it. Take the master, make a mold, make a rough copy and modify it into the new or highly modified shape. A lot of work is going in anyway so a basic shape is fine.

I am still using mine without issue, but the right temp is critical.
in the video I see the chap dosent watch the temp.
The more fluid it is, the less resistance to hold air bubbles you get.
Now there are another 2 products I have found, for quick small molds.
one is a 2 part silicone putty that stays hard after use, the other is from Japan and comes in a bag that can be reheated to go back to reuseable shape again Oyoshumaru or something like that.
It should be in todays mail, so I will let you know if it is viable for our uses.
Cheers

Is it Oyumaru?

[waaytoomuchintothis]

Did you guys look at the longer, better video he does as a sequel, after talking to the manufacturer? I still don't want it for car parts and bodies, but I see usefulness as a way to make scenery items.

[chappy]

Thats it Dan Oyumaru. I got it yesterday, but have to get the directions translated from Japanese.
It has something to do with heating it in water to use it for molding, but that was just from a couple of pictures. It would be for small items for sure. The blocks are not big, but for detail items like bumpers etc should be OK.
Do, you know anything more about it ?

I just bought some.
Hopefully it will have English instructions.
