comet flux

This flux is perfect when used with High Force 44 solder. Very smooth flow at the right temperature.

Gets the job done

I use this flux with the 355 solder to install rings in bolt noses, bolt handles and sight installations.. never had any trouble with flow.. ive brazed carbon/carbon, stainless/stainless and carbon/stainless..I clean the work pieces with acetone..I put this flux on a small piece of steel wool and hold with hemostats.. preheat the workpiece, rub a little on the work area and go to work.. Ive used it for years trouble free..

Get a bottle!

I bought this originally to replace a front sight ramp. seems like a waste to buy 6 oz. for a few drops. Yeah, if that's ALL it can do! I've used this many times, on many different projects. Automotive to the vacuum pump I repaired today. Any time you need to join steel, where excessive heat might be a problem, this is my go to. This morning, I needed to remove a broken pipe nipple that was loc-tite -ed in. problem was there was a check ball with a non-metallic seat nearby that was also loc-tite -ed in. Solution, I tapped the inside of the nipple for a bolt, filled the check ball passage with water, Comet flux, 44 solder, spun the broken nipple out! The lower heat required to solder has allowed me to work near many things that could be damaged by too much heat. And not have to worry about loss of temper either.

It can work

I bought this product last year when I purchased some Hi-Force 44 ribbon silver solder. I only used them for the first time this week when I was mounting a front sight base on a Mossberg 590. At first I used my regular silver solder paste flux with the Hi-Force but nothing would adhere after repeated tries. It eventually dawned on me that the solder was beading and flowing out before the flux did, so I switched to Comet because it operates at a much lower temperature. This time the sight adhered.
