I have a new in the box Blaser R93 LRS2 long range rifle in 300 Win Mag. Fresh out of the safe. Purchased in 2005 and never fired. Rifle is NIB and well know for its accuracy. Rifle is RH (wrong for me), but it's modular design allows you to not only easily switch calibers as but bolts as...
I have used both products for rifles and knives. Both work very well when you take your time, follow the directions (don't touch it until it says you can), etc. Given they choice, I usually learn toward applying the Cerakote. It is EXTREMELY hard wearing.

I have mounted Dednutz (dnzproducts.com) bases and rings on 3 of my lefty T3 lites. I have never had an issue with shift and repeatability. Huge fan of their products.

I agree with winmag, the White's are hard to beat. Big R usually has a great in stock selection right now and I think they are running $189.
Good luck,
