Absolutely my pleasure sharing this little tip! I actually found a very economical "Cling Wrap" window tint (20%) at Walmart for under $25 US, that had enough material to do two 14X24 inch bass drums, as well as one 14X22 bass drum. I believe the dimensions of the "Cling Wrap" material is 30" X 78".
It was located in the automotive section of the store, by all the third party auto add-ons (LED Dash lights, cell phone holders, etc.)
I also brought my Chrome Slingerland shells into a car window tint dealer, and asked him how much to apply the cling wrap to my bass drum shells with a nice tight fit, with no bubbles. After he grasped what I was talking about...he did a fabulous job of wrap-ping all 3 of my mirror chrome slingerland shells for only....and get this......$15 US. That's $5 per drum!!!
I hope this helps you out!
