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?

I've been using paste flux, but I'm looking forward to using this, especially to prevent fire scale.

Previously used Handy Flux, really loved using Cupronil instead (game changer). Handy flux is an opaque paste so sometimes it covers my solder seam making it hard to see where I'm soldering. Cupronil goes on clear (so no issue) & it was very easy to use either by spraying it on or using a tiny paint brush to apply it. Very pleased w/this product & highly recommend!
