another update... Got the oil leak fixed. It was hell b/c the previous mechanic stripped out the heads in about 6 of the bolts in the pan. I had to go grab some EasyOuts to get them out. Nevertheless, I did Git-R-Done'.... As for the stains, Im at a stand still. Isome remedies have worked a little but the stains are still visible. Im going to try this last product called pour-n-restore from Lowes before I give up. Im starting to think that I should have just paid the pressure washer guys to begin with?
