If anyone wonders which site is better, TDS or here, suggest you look at the TDS thread on this topic. Extremely positive on a great idea here, and what you would expect on TDS.
They did have a great comment there though. Are you worried about moisture and dirt getting behind the plate and causing either the aluminum or the plastic to rust? Granted, not a direct quote, but .......
I am confused..........I guess that was the only set of negative concerns they could generate.........
