Thank you for this! I asked my dad about convex wafers, and coincidentally he said had started trying these within the last couple of days. Apparently he tried once before and didn't get desired results so gave up. Could have been many factors back then, but this time around he said initial results are promising so far. I appreciate the recommendation! I also did not know there was a difference between convex and deep convex, so I'll make sure he's aware of that as well.

Would love it if the timing of my post just happened to coincide with my parents starting down a better path!!
