    I don't appreciate the attitude, Don.
    DUH Amazon was meant to mean DUH what can't you find on Amazon.....nothing personal DUH. I see a 30ML bottle for $21.00 and a six pack no size given for $38.95. A little goes a long way and if it saves one PAL AR it's well worth it.

    Alright guys! I cracked the code, I found the secret. I unlocked the magic. So.... You just need to follow these simple 7 steps and you are set to go.
    Step 1: Metal Blocker
    Step 2: Super adhesive blocking pad
    Step 3: 2 Staggered Anti-Slip Discs- preferably DynaGrip Xtreme
    Step 4: Block lens
    Step 5: Put lens protecting chip on backside
    Step 6 (optional for high minus/ high base curve lenses: Regular blocking pad with the paper still on it
    Step 7: Use regular scotch tape to secure the front in a box formation.

    This is now the next question... I have found some reject blocking pads - probably from the early 2000s or late 1990s- that are super sticky and the quality of them is like no other blocking pad I have tried, even through Opti-Source. So please tell me what they are or what is comparable. They are 24mm by 22mm with a 5mm tab and powder blue protecting paper, I will try to post a pic. I use 3M 1692M right now and for normal lenses they are okay, but the old ones with my 7 step system didn't budge AT ALL even on a -6.25 (sph) -2.25 (cyl) Hi 1.74 tinted, mirror coated lenses with premium BSAR.

    Or. You can get an MEI EZFit NBL and be done with all blocks and pads.

    The product is out of stock in the US for the distributor with which I placed the order. At this point it will be a little more than a month until I get it.
