I watched a learning video and this was used so I had to have some. It's like a miracle if you hate fire scale like me. You need this!

So easy to use. Spray and touch up any spots with a small brush.

I really like this Flux. I had been using the Handy flux, which is ok. But this works better and is a good fire scale protection.

I have seen this used in videos and looks like it worked great. I haven't had much luck with it unfortunately. Probably user error?
