Viz-Torque Tamper Detection Marker Red (20241)

I use it for all the critical bolts and nuts on my cars, truck and RV. Easy to use and visually see. A must have for critical components.

Great tamper marker

I've used a variety of marking products when working on my vehicles, but this (new to me) product is by far the best I've used. This color is very easy to see, the product is very easy and CLEAN to apply. I love paint pens, but they can be a pain and make a mess quickly. This is my go to now for marking torqued bolts.

Compared to DyKem CrossCheck, this stuff is a little cheaper, but works all the same. I use it for critical fasteners on race vehicles and offroad motorcycles. Unless it's placed directly into the path of abrasives (road debris, brush, etc), it really doesn't come off on it's own. A needed quality considering what this is used for. Comes off easily enough with a pick and brush when it's time to work on something. The brighter colors for the most part appear to be light fast. I haven't had too much issue with fading.

works as intended

Easy enough to use. I wish the consistency was a little less putty-like so you could put a more appealing looking bead on the thread; it kind of "stretches off" as you remove the applicator from the site and tends to leave a little Alfalfa that's difficult to get to lay down. But it's a nice thing to have on hand and gives some peace of mind for things like upper strut mounting studs and things like that.

Works good
