Black Tar? More specific please!
Pitch based?, Petroleum based?, polymer based?, bituminous based?
.................Iron Helix
Ya left out heroin.
Same stuff used for foundation, I dipped the bottom of my garage door trim in it and then wrapped with coil stock. I was trying to protect it from wicking moisture.
Thanx for the help, Lou
I'm guessing that it is a bituminous (coal) based coating or a petroleum based coating which would not normally corrode aluminum.
Was the wrapped wood CCA treated?
But keep in mind that aluminum in contact with moist concrete can pit by chemical reaction with the alkalines leeching from the concrete or by reaction with organic acids from accumulated plant debris.
Are you seeing a problem or just worrying about a potential problem? Why did you post the orginal question?

Iron, I coated my garage door legs with tar at the bottom and then wrapped with coilstock. Thought it would help with rot. The floor is not poored yet

was it a bad idea?
put a barrier between the AL and CC...
ie... a rubber weather strip..Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming<!----><!----><!---->
WOW!!! What a Ride!Forget the primal scream, just ROAR!!!
wrapping was probably not a good idea, depending how you did it and how it attaches.If you have any surface edges pointing uphill, there is a way for water to run in between the door and the metal to become trapped. If you used nails or screws to hold the metal on, you provided a a point of entry for water to get inside the wood and be trapped.Most of the foundation coatings are emulsified, so the tar probably won't hurt the coil stock. it will still be there after the door rots out from behind it.If I were you, I would drill a 3/16" weep hole in th ebottom every 12"
