I don't remember where I heard about this but I tried it and thought I would share... You can make a filler putty out of styrene weld and pieces of styrene. When you are almost out of styrene weld (so low that the brush doesn't reach), toss in a few pieces of scrap styrene. I used the tree that held parts. The weld will melt the parts making a syrup of putty that will flow into cracks. And being made from the same stuff as the model, it sands and cuts EXACTLY like the model. And, before it dries, you can mold it into shapes. You can even force it to flow deep into cracks by slathering it with weld. Give it a try. It works and is a great recycle of stuff you would just throw away anyway. John

Great tip John. I heard about this, but never gave a thought to tryin' it, mainly because I have no styrene weld. I'll have to get some.

Acetone from the hardware store will also work (and is very cheap) but it really stinks.
And get some styrene weld. Great stuff for clean modeling. I like Tamiya's weld as it has a sharp brush and comes in a square bottle that doesn't spill easily.

I do this. I chop up bits of sprue and mix it with Weld-on #3 (which I use as my primary liquid solvent/glue).
The only drawbacks to it are:
It takes a long time to fully cure (24 hours at least)
It can be a little stringy, which is annoying, but you are going to sand it down anyway, so no biggie.
Sometimes I get pin holes, but that may be from mixing it before use. I need to pay more attention and consciously try it without stirring or mixing it.
Other than that, it's cheap, easy to sand, easy to scribe, and easy to glue other parts to with your plastic solvent.

A question: does it HAVE to be mixed every time before you use it?

No, not really. It stays suspended surprisingly well. But light mixing (not shaking because it adds bubbles/pinholes) while "slathering" is a good idea.
