Sanding and painting an iS lip

[matt325is]

I removed the undercoating on my sides and rear skirts, it was a PITA, but looks VERY good in the end. I used primer, Dupont colormatched paint, and transtar clearcoat. I have an HVLP paint gun as well. I would like to take the undercoating off my front spoiler as well, but have not got around to it.

You dont need flex agent for anything but a front lip/spoiler. I have never used it, because, i can bend my lip and the paint won't crack. when i hit it on stuff, it will just scrape the paint off, even if it did have the flex agent.

How would I go about getting the undercosting off?

And, if I wanted to hold off on that, what stuff would I use to repaint the undercoating black?

If I repaint my front spoiler, I'm guessing I should sand that down first, start with some low grit, and work my way into the high grit. Then, get primer on there, and use paint purchased from euro depot or paintscratch.

I'd really like to get the undercoating off sometime in the future, but for now, I think I'll jsut touch up what I have.

Yes, the rear spoiler needs a flex agent - it is actually quite flexible - I can push in a little bit with my finger.

You can use paint stripper on the is spoiler. Makes it tons easier to get all the paint/primer off with alot less work.

Wouldn't work on the is rear spoiler (I already tried)

So, sanding the rear spoiler is the way to go then?

yeah, I think if you use a really strong paint stripper it might melt the rear spoiler.

Oh yeah, be sure to get the correct gloves to handle paint stripper. You need ones that you get in chemistry lab. latex ones WILL MELT!

When i bought my car, it had the front spoiler on it, and Eric said when it would get some chips in the paint(from road debris) he would just hit it with a few shots of black paint. So I did the same for a while. This never would last long and i found myself doing this often. Got tired of it, and decided to try to do it up right. So, I sanded it with oh, I don't know, prolly some 220-400 grit and got as much of the old paint off as possible and as smooth as possible. I just used some Dupli-color gloss(Disc. Auto Parts) and sprayed about 4-5 good coats on it allowing each to dry for several minutes. I finished it up with a 2-3 good coats of clearcoat(again allowing each coat to dry) and it came out great. Not only that, but the finish has lasted soooo much longer than before. Touch ups will almost certainly be inevitable no matter how you do this, so just accept that. If you screw it up(hard to do), don't sweat it, you can always do it over. :)
