Sounds good. Please tell us what you used.
Do you have an issues with peeling? The only paint that is peeling on my car is the rear spoiler. Ive been meaning to remove it and get it painted. A local shop wants $100 to paint it. I am thinking about doing it myself, maybe black. What would be a good type of paint to use?
I don't have anything peeling, mostly paint bubbling in places. Do you have pics of your paint peeling? You sure your rear spoiler wasn't repainted at some point in time? Does the paint look the same, texture-wise as your roof?
If you were to repaint the rear spoiler, I'd go with the same single-stage paint that's on the car.
Here's a test you can do, BTW, to see whether your spoiler has a clearcoat. Go to AutoZone and pick up a thing of Meguiar's ScratchX. ScratchX is a light abrasive that will remove light swirls and some oxidation and thus will take off a bit off paint. We can use this to see what kind of paint you have.
Using a soft light-colored applicator (make sure it's not yellow), work in a dime-sized amount of ScratchX to your side view mirror (work it in with circular motions with moderate pressure). Then using a soft microfiber towel (also do not use a yellow one), buff out the side mirror. You should see yellow stains/traces on your applicator and towel. (And also a shinier, less-faded mirror).
(Instead of a side view mirror, you can also use an inconspicuous area somewhere, e.g. a bottom corner of your rear bumper).
Then try the same thing on a section of your rear spoiler (away from the part that's peeling). Work in the ScratchX with the other side of the applicator (that's still clean and has no paint on it) and buff out with a side of the towel that hasn't been used. Look to see whether you have yellow paint on the towel or the applicator. If you don't have any yellow paint, your spoiler has paint with a clearcoat. (If you do have traces of yellow, then you have single-stage on the spoiler.)
Be sure the surfaces are clean before you start using ScatchX.
Also, if you want to double-check the logic, find a car with clearcoat (90% chance for most cars) and do the same test... if the car has clearcoat, the towels will not get any paint color on them (because clearcoat has no color).
