Since I've known the car and owner for many years, it always bugged me how the rear tail panel and lower quarter panels had this icky build up on it, making the back of the car look dingy as heck. Always mentioned to the PO that I can help him clean it up. Most likely years (decades?) of oily road grime and needless to say I couldn't help myself.
The post cleaning pictures are above in the previous post. The product used is shown in the photos below, which is a citrus based tar remover.
Befores:
In this one I had already started on the lower half before deciding my ownership of this car could be photo-documented. Mr. CEK inspired me, but my threads won't be nearly as epic, however

Product:
I've had this jug for about 5 years so hopefully it is still in production since it works very well. Too often crap is reformulated to make it cheaper to produce and never works as well. I literally spray it on and wiped off the residue in seconds. On one section of dirty portion I spent 20 minutes using rubbing compound to cut through crap-- it was so hard I thought it was black spray paint! Good thing I remembered to give this product a try.
