Kemp, imo, u should seek out some sort of providing contract with these people. Well all reviewers should.
I mean the stuff isn`t exactly ~that~ expensive. But a single mention of the kind of goo u used each time u did a review has got to be worth it.
30g tube tho for some1 using it everyday has to be good.
Would it go "crusty" if u didn`t use it as often ? Dunno tbh.
