What is the BROWNELLS - DICROPAN T-4®?

DICROPAN T-4 ROUCH-UP LIQUID GUN BLUE


T-4 is in the catalog because of customer demand. As Maynard Buehler said: "THIS is the BEST yet." Every time a new gun blue comes on the market, we test it on a piece of gun barrel. We blue three spots: one with the new blue, one with Oxpho- Blue™ and one with T-4. One day later we start rubbing all three areas with steel wool until one of them starts wearing off. So far, Oxpho Blue™ is toughest and T-4 next. However, for ease of application and deep density of color, T-4 is superior. Its ability to touch-up wear areas and scratches instantly has made it a favorite.

Great Results!
For years, I have been a big fan of Brownells 44/40 and have used it as the standard for testing other cold bluing products. I had also previously used the "creme" version of Dicropan T-4 and did not particularly like it. However, I now have to say after doing fairly extensive (non-scientific) testing of the Dicropan T-4 Liquid that I am replacing my 44/40 with it. It not only works as well or better than any other I have tried, but it is also less expensive!

Great alternative to cold blueing
This is a great product for touch ups and blending in dings or scratches. Like the directions say, prep is crucial. Clean/degrease area, then dry. Wipe/blot on (a saturated Q tip works great) let sit for a few seconds. Then wipe off with same bore cleaner/degreaser. Then I found you can rub in a little oil to seal in the color. Not so much for complete bluing, but deffinetly great for touch ups and blending any scratches. This sets as a really nice 'dark black' color when done. Works with carbon steel only. Hope that info helps.
