Its cross check. Cant mess this stuff up very bad.

Quick ordering and delivery of these units. The product works well and we use it to validate warranty claims and to alert us if the customer has gained access inside a unit.

Very easy to apply, works well

Makes pre flight and annual inspections easier.

Easy to use and apply. Bright red color is easy to see. Cures quickly. Cleans up with acetone.

As described and does its job fine for the purpose Im using it for.

This is a great product for a great price and outstanding fast delivery.

Works great for our students s projects.

Couldn’t be happier. My tube of yellow flows perfectly. Its very distinct and actually exceeded my expectations. I don’t know about the other reviewers, but Aircraft Spruce solved every problem I’ve ever had with any of the products they sell. What’s to worry?

Flows a little too well in my opinion. An additional cap, with a graduated tip that you can cut to size, would probably solve this problem.

Very nice product. I had one tube that was defective (hardened up). Once Aircraft Spruce was made aware and they promptly sent me a replacement tube. Very good service

Product is great. Be careful when ordering this product. It is considered hazardous and doubled my shipping rate. Cost me 3 times the cost of the product to ship.

The flow is either to much or dries in tube! Bring back the F900 in the plastic tubes. It worked great for years! This stuff is horrible.

The flow is poor, applying this product can be difficult at times, I have seen where the product did not adhere to the vehicle, thus the fastener loosened and there was no break in the safety seal

Almost total crap. Worked fine for the first application. But when trying to reuse it one month later the contents were totally gelled and useless. Yes, the cap was clean and tightly secured. This same thing also happened with a second tube. Bring back Torque Seal.

Have been buying torque seal many times. Unfortunately I did not have catalogue in front of me so ordered 3 tubes as they are usually small and around a couple dollars. These t urned out to be quite a bi t larger and more expensive and may spoil before using as they tend to. dry out. Wpould have appreciated if salesperson would have mentioned the larger size

Drys up in tube, tube cracks easily. Bring back the smaller plastic tubed product please!!!

Not near as good as the F900 was. This is the second tube I have ordered. First was impossible to use even after cleaning tip, finally just ruptured. This tube has opposite problem, keeps flowing after small squeeze.

Tube was creased and cracked - continues to flow from tube once squeezed

Product wouldnt dispense through the tip, tried to clear out with pin, pin came out with product on it, but never worked.

Something was wrong with the tube and wouldnt dispense. Stuck a thin nail down through nozzle in case it needed puncturing and would get paint on the nail but couldnt squeeze any out. Tube ended splitting trying so hard to squeeze out paint. Dont waste you $4.50.
