Looks like you did a good job to me. Now if you want to have it shine you will have to buy a professional buffer / pads like the Porter cable and some poor boys swirl remover,polish,wax. These items are a little expensive but with the money saved by doing the inexpensive paint job it will be money well spent. I just bought a new Porter cable buffer for $106.00 shipped from the company.

If you haven't seen Aussie Drivers updates i urge you to take a look at his results and see for yourself what a shine that can be had with the right materials and some quality time with the buffer.
