Hey I will try to keep you updated on the lasting of the QS ruler. It has been used in the shop daily for about 2 months now. I have not noticed any degradation in the coating. Personally I don't have problems with reading it...biggest adjustment I had was going from a 6 1/2" x 24 1/2" ruler to a 6 x 24.
EasyPeezy I wish I had put Nexcare tape on my rulers when they were brand new...I think then the markings wouldn't have worn off! It does help, doesn't it? I think the markings on the QS rulers are between the ruler and the non slip coating. I'm not getting rid of old rulers for these new ones. I'm way too conservative for that.
