Well wax - not candle wax - you can get in a lot of different types. Some are good for filling, others are made for milling or carving and others are made for glueing. Well when I first read an article about wax I dug a little deeper and found that all those dentist model studios are using wax to make the models for your third teeth and what works for them should also work for scale modeling ... and it does, if you ask me.
Not only for filling you also can use it for carving some small add on and alike
The only real thing one have to take care about are the silicone grease inside the wax - so it needs a good cleaning. Once dried out I didn't have any problems with this so far.
just some small examples:
The gray stuff to fill the seams is filling wax
The red stuff is milling wax - the kit did not have an IP cover delivered
filling wax again to fill in the wheel well of the vac kit
So, there are tons of different possibilities.
