Ya I couldnt find 5/8 in a good grade at home depot here either. I bought a low grade, but once the laminate went on it's fine, you cant tell at all. Only extra thing I had to do was wood fill a few knot holes.
Did your 3/4 T-Mold sit flush with the Laminate and the 5/8 ply?
The reason I ask is, I recieved my sample 3/4" T-Mold from T-Molding.com but after installing it in a 3/4" ply test piece I have about an 1/16th on each side that is sitting proud.
I just recieved the 5/8" samples but have not check them in the test piece yet.
I also havent been to Home Depot to check the thickness on the Laminate, I was going to paint but after all the "looking back" advice here, I will probably laminate especially if its a 1/16" thick
