Pros: Home remedy before you take it to a paint/body shop. Easy to apply.
Cons: May not live up to expectations. Pricey.
This opinion is written for Turtle Wax COLOR CURE, the one that comes with a lipstick-looking "chipstick." There is no separate category for COLOR CURE, so I'm placing my review here. I am assuming that COLOR CURE is the updated product for COLOR BACK. If it isn't, it's probably a very similar product.
I have a dark green car that some punk "tagged" one day at a local park or on the street in our neighborhood. The scratch marks look like they were made with a key or another sharp metal object, but they are rather thin. Since I take pride in the upkeep of my car's appearance and mechanicals, the marks were devastating (not to mention the awareness that our neighborhood is going down the drain...)
Anyway, I was watching cable at my in-laws' last weekend when I saw an ad for Turtle Wax's Color Cure polish. The ad claims that the color-specific Color Cure (comes in Black, Red, White, Blue and Green) hides minor scratches and enhances the paint's color. There was a segment where a key was used to scratch a painted surface which was immediately restored to near-perfect condition with the use of the chipstick and an application of Color Cure polish. It's similar to the approach used by advertisers for GS-27. (I tried GS-27 in a small part of the car but it dulled the paint. I had used it before on a white car and it worked fine. Too bad it messed up dark, metallic paint.)
I went out to get a bottle of green Color Cure, which was hard to find at discount stores that tend to carry only white, black and red. I found mine at Pep Boys for $7.99 (Apr. '01) + tax. I consider this a bit on the high side, since you can get a bottle of good Carnauba wax (Meguiar's Yellow Wax) for about the same price. I washed my car and followed the instructions for Color Cure. I applied the chipstick to fill in the scratch marks and wiped off the excess. Then, I applied Color Cure polish, waited for it to dry to a haze, and bufffed it off with a clean towel.
The results: The scratch marks are still there. They are slightly less noticeable because the white lines were pretty much filled in with the green chipstick material. The polish itself did not perform any miracles claimed by the television ad. I applied a second coat of the polish, and the results remained the same. The scratch is still visible, but it doesn't stand out as much. The improvement in gloss and color enhancement are hard to detect since the car's paint was in good shape. It may have covered very fine "spiderweb" scratches, but my car's paint was in good shape to begin with. Its benefits (if any) may be more obvious on dark-colored cars that are frequently machine-waxed or polished. In a month or so, I'll try to apply another coat of the chipstick to the scratches and another layer of the polish to see if there are any improvements with added applications.
Color Cure is easy to apply and buff off. I've tried Meguiar's Polish as well and this is slightly easier to rub on and rub off. The only thing is that it's heavily dyed in green (or whatever color you buy) and your towels will get stained with that color. An additional note is that the polish does not repel dust. It doesn't claim to, but I thought I'd mention it since it got real dusted up when it got windy just the next day.
I like the easy application and slight improvement in paint condition. BUT I am rather disappointed that Turtle Wax, a trusted and "serious" brand, would resort to advertising pitches used by "As Seen On TV" products like GS-27. Of course, I was skeptical, but I thought I'd get better results from Turtle Wax than what I got. Don't buy this product if you're intent on fixing "keying" scratches or other damage such as nicks from shopping carts or parking boo-boo's. If you have a car with paint in miserable condition, this may be a product if you want to shell out the $8+ dollars. Otherwise, Meguiar's, Mothers, or the regular line of Turtle Wax polishes and waxes will be safer bets.
