No, just the tape several years ago to stop a small water leak and it didn't work as advertised.
Anyway, it takes a fair amount of mass loading to damp them, though not as much as the cabs proper. FWIW, I filled them with kitty litter and it seemed to be as good as the much heavier sand recommendation done by the then local distributor's inhouse pair of 'pallet' kits.
If you choose to use it anyway, recommend loading it with sterile sand or if it's thick enough, small gravel, otherwise just stiffen them a bunch using MDF, old ceramic tile or similar heavy scrap stuck on using PL400; just glob on ~ball like blotches and slap it on, rotating it back n' forth a bit to seat it, i.e. don't squeeze it out of the joint, just let it 'float' to make a constrained layer damping' node [CLD].
This became my default way to deal with damping limp stuff after trying it on the backside of a cheap one piece bathtub/shower insert back in '82?. It still feels as rigid, solid today as the old cast iron tub the day after I did it and still with no stress cracks.
