I can't find any fault at all with what Seige has said in his posts ( which is usual I have to say, great minds think alike and all of that

)
Why on earth bother to find a substitute for something that only costs a couple of pounds and was specifically made with us magicians in mind?
I bought a small pot from magictricks.co.uk for about £2 and it's so far lasted a couple of years. I'm pretty sure that dentists wax will put you back at least two or more times this cost. Anything that you have to put in your mouth will have gone through so many labs to make it safe, you will no doubt pay the price for all of this at the pharmacy counter.
There are some things that just are not worth the effort and this is one of them.

It's not really an optical illusion - it just looks like one!
