Not sure if anyone else has had to deal with this....I need to remove the plexiglass from my homebuilt cab due to the buildup of dust "spots" on the inside, between where the plexiglass and TV screen are. My cab is coming up on 1 year old this summer and I've noticed that the dust spots on the inside are getting so bad that I need to open it up and clean it (not easy to do). Anyway, I was wondering if anyone has had this happen and if there are any products I can use to help prevent it. Thanks for your input...
