I noticed from a prior washing that my car's paint was peppered with those annoying yellow spots from salt and other residue from our hard on paint winter. I gave it a couple of shots of TRIX which was covered in a previous post but that stuff is just difficult to work with and smells horrible, although it does get rid of most yellow spots. I thought I would try a different approach.
So I gave it a good washing, applied the clay bar and then started on the polishing using Nu Finish. I was going over all the polish options at Crappy Tire but settled on Nu Finish for two reasons.... the price was actually on the high end so I thought it would be good and a customer there said he uses it all the time and it works great. I applied it to one section and started rubbing to see if I could get out the yellow spots and sure enough they started vanishing. The only thing I will say is that this took a LOT of elbow grease, two hours worth of rubbing in a circular motion, but the results were great. I also got rid of several surface clear coat scratches with this product.
I followed up the polish with a good application of my Poor Boys Sealant and the car was looking as good as new (except for the bumper damage). Although I used up the better part of a full afternoon I removed almost all the yellow spots, got rid of several surface scratches and shined up my Optima beautifully. Next time I may buy a DA Polisher just to make it a bit easier for the polish application. I also have to do my better half's car.
