So I made my first batch of home made FSG last week, and have used it several times. I LOVE this stuff!! Each time I have used it, I have layered a bit of BRHG on top for hold with good results. My question is, because I have so many other products at home (and feel guilty if they sit collecting dust!) - is there anything that you have found that does NOT work well with FSG?

I know I should be happy I found something that works so well, but I can't seem to help myself from experimenting! So if anybody has any products that didn't play nice with FSG....please share!
