you should have bought one of the painted decklid spoilers in the first place if you are on a budget - and now that you have $ invested - what is $100??? come on - dont be cheap

I cant wait to see pics of the end result of you DIY painting if you are asking these questions in the first place...

If you screw the clear coat up and don't get a mirror finish (glassing the paint) you either take it back down and start over from 100-320,prime, finish sand 400-600 and repaint until you get it right, or you wet sand it out with 600-2000 grit and buff it out. Yes you can hand polish but you cannot get a mirror finish by hand even on a part that small. Can you get close, yes - but a buffer (a real buffer not a porter cable) can do what no hand can do. No painter makes money on buffing, but few armatures get away with laying glass. That's the difference between a paint shop that does reputable work and work that's just, "hmmm, yeah it looks ok".
I guess you'd take it to the next level. I just wouldn't spend two times the money on sand paper and paint than I did on the lip spoiler. For something larger, like a bumper, I would definitely do it all the way or have it professionally painted. Probably professionally.

but the point of doing the paint correctly on this piece - it is RIGHT IN YOUR FACE and any defects are going to be easy to see

Now my question: I'm looking to paint my trunk lip spoiler, but don't want to pay a shop +/- $100 to do it. There are a few online retailers who sell spray cans. I need titanium silver metallic for a 2004 330ci. I took a look, but didn't see any particularly recent threads on this subject. Any recommendations would be greatly appreciated. Thanks.
I would just like to say that the success of a spray job is in the preperation of the surface to be sprayed and the conditions during the spraying process. That's what you get for your money in a body shop. You can save a few sheckles by doing it yourself but I would let the pros do it.
