Resin weirdness...

[Hammers]

I pour two part resin into a hollow compartment within a ship model the other day to make it heavier and a bit more workable. The resin was probably a bit off (old) since it bubbled up through the pouring hole overflowed its sides. It cured allright though. Now, a few days later the resin is leaking some oily substance and where ever that happens the acrylic paint won't stick. Why is the resin leaking? Is it poorly mixed or beyond its expiry date?

A bit of both, you can get lumps or congealed bits in one of the parts and if it's older then the use by date then they don't tend to mix 100%.

It happened to me years ago when I was first making my Japanese walls, the outside got hard like a crust but the middle stayed soft. I poked it a bit too much and it came spilling out of the top. It took a good year or so to go off properly and it now looks like some sort of plant growth on the top of the wall  so it turned our for the best.

There's not that much that I know of that's a cure I'm afraid but some here might. Do you have a photo to show?

It's not for the Arumbaya tug is it

It is but it is not so bad. Annoying at the most.

it happens also if you mix it in a not perfect enviroment: you can't use it whit a humidity which is too high, and also the room heat is important!

Anyway, it happens ... that's one of the (many) resin issues i've to live with...

happened to me to, got 2 bottles of 50/50 resin the one I opened last year got crystals in it bit like a honey jar, wen I mix that the resin gets first oliely then very brittle, the other 2 bottles that I got at the same time no problem , from what I heard it absorbs moister over time and that is what makes it that way
