HHIP 8030-8355 Dykem Hi-Spot Blue, .55 oz. Tube

Perfect for “spotting” hand scraped machine surfaces. A little goes a long way. Invest in a good rubber roller with ball bearings if possible. The cheep ones fall apart when rolling out the ink.Functionality:Works

This stuff is great for finding high spots between fitted parts -- which of course is what it's made for. I found its results clearer than when fitting with Prussian blue. I used it to fit an Ed Brown pistol barrel to a 1911 pistol. The barrels are machined slightly oversize to accomodate fitting into 1911s from different manufacturers, so finding the high spots and filing them was part of the installation. They recommended using a black marker, assembling, and looking for removed marker. I couldn't get the fit until I used Hi-Spot Blue, which made finding the high spots easy.My only complaint is that for a tinkerer like me, this is a two-lifetime's supply. (Since it is non-drying, it will probably be fine at the estate sale.) I'd like a small container about one quarter as large. Working machinists swear by this stuff, and would probably go through a couple of tubes a year.

This is the de-facto standard for checking interference points or painting a surface to make a scribe mark without actually scratching the material.The kind that comes with a brush might be a superior form if you're clumsy or not thinking like me. The tube WILL ooze several dallops of Dykem when you pierce the tube with the cap, and if you're not wearing gloves and also doing this in front of a fan, it WILL get everywhere.Acetone will clean some of it, but there will still be stains on everything it touches; hands, clothing, shop floor, you name it. Ask me how I know!

Nice blue for my projects

Did think you could still get this on the market.Well done.

i was trying to fit a stock to an action and i didnt know what was holding things up. put some on a few suspect areas and it let me know real quick that i needed to grind in these exact supot. time saver, but it is messy. so wear gloves !!

Been around forever because it works. Great stuff to work with and always constant.

Works exactly as it should. Just don’t do what I did and squeeze on the tube while poking a hole in the top….quick way to make a mess. Completely operator error.
