I found a short Bong brush at Lowe's Home Improvement store. I already had an acid brush attachment for the pole. It fit perfectly. I used a shoe string to tie the Bong brush to the acid brush. After tying it together, I gave it a try. It works.
If either brush is ever needed for another project, just untie it and you are good to go.
It's August and it won't be long before the leaves will start turning and falling. I'm ready for it.
