Good quality markers

Great stuff for marking bolts. I've had some bad tubes before that would burst on the back end that I got from a local dealer as perhaps it was older. I've purchased two on Amazon and they have been performing great.

Save rechecking torques, ensure warranty builds

I like using this to mark bolts I have final torqued as I build an engine over the course of weeks. It keeps me from having to double check myself. This is air dry use only. Not for use in oil wetted areas, coolant passages etc.

Great visual indicator

Found out about this through a helicopter mechanic at work, it works well

Crimp It

Works great. Pinch down the tube's tip in order to reduce the size of the paint bead.

Already paying dividends

I run on the track. Got over 40 days last year and that is a lot of vibrations on the car and taking things apart to replace or inspect. With this product I can visually check multiple items quickly and verify the fasteners are tight.

Does what it’s supposed to do

Easy to use stays on great. Breaks when you I do the bolt.

works great

Bright, no drip and easy to use to let you visually know when bolts or nuts are tight. I'll be putting this on everything I wrench on.

Quick Inspection

I use this on my 4x4 when replacing parts so that I can easily take a look underneath after a day of offroading just to double check that no bolts are coming loose. Especially great for critical things like suspension parts and drain plugs!

It works

Always use it, it's hard to find locally.

Awesome product

I put it on my race car fasteners, it did a great job to indicate a losen bolt, and give it a professional look at the same time.
