I am getting ready to try to repair some coils and can not find any tar locally. Does any one have some that they would sell?
The next time you pass one of stinking flat roof jobs with the tar pot( the trailer hooked up to the propane bottle, emitting the stinky smoke), Stop and ask the guy for a few chunks of his tar.
Scott, I sent you a PM, jb
It is actually pitch, which is different to tar as tar will not set solid.
You could look at junk yards or scrappers for very old power pole transformers, say pre 1970 ?
You should be able to save, melt and re-use what you dig out of your old coils too.
This has been discussed many times here. It's Type III steep slope roofing asphalt. Most refer to it as 'tar'. jb
From Ron Patterson, August 15, 2009 - 06:55 pm:
"I just believe it is better to stick with the original tar (Ford call it "Hydrolene", a fancy name for the very bottom end of the crude oil cracking process) and avoid any possible trouble. You can easily obtain original style tar (go to the roofing supply store counter and ask for Type III Steep Roofing Asphalt and they will assume you know your business. It usually costs about $10 for 50 pounds or if your clever/cheap ask them if you can rummage around the storage area and find a 2-5 pound chunk which they usually don't want to deal with. I use five of these 50 pound chunks per year.), it is cheap and easy to melt a small amount in a coffee can over a hot plate. And remember if you use your wife's stove to heat the coil tar, that only works once! You do so again at your peril."

There is a very high probably that the old transformers contain PCB's which have a high risk of causing cancer. Having spent 12 years on the board of directors for power company we learned how expensive it was to dispose of these dangerous transformers. Please don't go near these old transformers.
