[I Vtec, do you?]

I mean aside from fixing rock chips. I wasn't sure where to put this, so here it goes.

I bought a new spoiler for my car. One place quoted me at $120 or so to paint and install it, now they want $350 just to paint it. So far, this is the cheapest quote I've gotten, some ranging all the way up to $500 for it.

Obviously, I'm not going to pay that. I was thinking like $150 for paint, $50 for install. Apparently that was way off.

I'm thinking about just painting it myself. I figure if it doesn't work out, I can then get it painted and there will be no problem. I'd like to try my hand at it first, though, just to see if I can. My plan was to buy a bottle of matched spray paint from paintscratch.com, along with clearcoat spray and the rubbing compound to make it smooth. In theory, this should provide me with a professional look. However, looking at my previous painting experience, the rubbing compound has never smoothed out the finish like an OEM paintjob. Maybe the paintscratch stuff will be different? I'm not sure.

Anyways, anyone have some advice on how to approach this? I don't want it to turn out like crap, so I might have to concede and pay the outrageous amount for it.
