Also .....Had a little set back today........I took the Grill Assy apart and was cleaning all of the Red Clay dust that had discolored the back side of the Grill over the years........the Grill was perfect......I used Royal Purple Degreaser and with a lot of scrubbing it cleaned up pretty good......after rinseing it off I turned it over and this is what was waiting for me
The cleaner must have a mild acid base to it and it seems to have attacked the anodizing.....time to strip and re-anodize.......So if you use this stuff around aluminum

.....be careful.........
