ATM atm tube black

[Adams <adams@rmci.net>]

     I found an old unused spray can of rubberized undercoating in my 
garage.The contents are petroleum distillates,xylene,propane and 
isobutane. This stuff lays down well and when dry leaves a rough flat 
black surface. I am thinking of using for inside my partial alum. tube. 
Anyone have experience with this stuff or comments? Its made for Napa 
automotive parts chain by Macs ( Ashland oil).  Also, concerning my 
previous post, thanks to all for suggestions on wood selections.
