Putty
« on: August 27, 2024, 09:39:23 AM »
I've just had a right disaster with Milliput.

First off, it turned up looking quite odd. It had a gangrenous green crust on one of the sticks that I don't remember it having but the real trouble started when I tried to apply it to the model for some welds. It just wouldn't adhere to the model and moistening it turned it into a non-adhering slurry. The resulting job looks awful; out of scale, without any consistent shape and with varying consistency.

I'm thinking of going to Tamiya putty after this, I have better experiences with it. Does anyone have any Milliput advice?

Sounds like you got a bad batch. Or it was too old. Did it get stored in a place that was really hot or cold?

I don't know, it came to me a week ago from BNA. It's been a cold Australian winter.

You can sometimes revive 2 part epoxy putties by heating them (a few seconds) in a microwave or an oven. Your mileage may vary.

I’d contact them about it. It might be a bad package or if it’s a storage problem they need to know about it so they can fix it. Either way they might send you a replacement.

Milliput goes like that when it is old.. got some in the filler drawer. Generally it is just a matter of working it harder to warm it up. Never been impressed with its adhering qualities nor workability, I find it a bit too grainy.
There are a number of "improved" products on the market in that space of two part Apoxy putty/filler/sculpting medium.

I moved to Aves Apoxie Sculpt for things like weld beads (when I don't used thin stretched sprue, softened with glue and worked), making Tarps, small gap/seam filling.
Same deal, mix parts together, smooth off with damp finger/cotton bud/tool. Rock hard in 24 hours. I have a batch of this that is now approaching 5+ years old and still good as new in the tubs
