Roof cement

[beatrix1]

The previous owner of my 73 Overlander used black roof cement of some sorts to patch over where the antenna was. It is not only ugly, but brittle. Any ideas of how to remove without damaging the skin underneath?

Hair dryer/heat gun and a plastic putty knife. The heat should soften it a bit, and the plastic won't damage the aluminum skin.

Plastic putty knife might not handle the heat, if you use a metal one you might be able to direct the heat at the blade and with a low angle slide it under the roof cement. Tar is flammable at high temp, might be prudent to have a fire extinguisher handy.

I removed some with solvent from a parts washer before. You have to take your time and let the solvent soften the tar rubbing with a solvent soaked rag. Mineral spirits may work also. It will completely remove the tar and leave you with bare aluminum. You will need lots of shop rags.
