Polishing lines

Hi all,

I bought my black 55 plate z4 a few months ago. When I got it there were a few shallow scratches on the bonnet I attempted to polish out using t-cut (as I had done successfulkly with the mini that I traded in). The scratches are better now, but I have rubbed patches in into the paintwork by working too much the same direction I think. What would be the best way to sort this problem, which is most obvious when I have cleand the car and the light bounces off it. I'm worried that by polishing in cirlces I will make it worse.

Any suggestions?

Thanks
Pedro
 
Pedro, this may do better in the Detailing section of the forum. 20Ducks can probably help you out with this as well as others. Black and darker colors do show small flaws fairly easily unfortunately.
 
Moved... mine has the same. The previous owner used wire wool by the look of it (ok, so a slight over exaggeration there!). I am interested in how to fix it too.

the finish from mine straight from the dealer was crap, I have used my PC with some very mild products to remove
 
The process of removing scratches, spiderwebs and even straight scratches is all performed by preparation, the right products (compounds and all the variations of compounds), tools and technique. If done correctly, what is truely performed is that larger scratches are made into smaller ones, then those are hidden. Ergo, start out with the appropriate compound, then glaze, polish, wax/protectant. Without seeing what you need it is impossible to recommend which product. Whatever is necessary to bring the surface to where you want it I would suggest that you use a random orbital such as a Porter Cable. Using an orbital polisher should be left to the experienced only.
Once the correct surface condition is achieved the maintenance will then be a proirity. Using an incorrect drying method, contaminated water or wax/protectant applicator for example, will promote the potential for scratches.
If unsure, get together with a professional or join a car club and ask for advice from an experienced detailer type person. You could learn how to do your own vehicles and make some new friends in the process.
