I've always had any eye on the M3 trunk spoiler that other owners have installed. I found an unpainted lip off of eBay and order some color match spray paint to give it a try.
Initial test fit looked very good in my opinion (see above). It looks clean and nearly stock like. So I started to prime, sand, and apply the base coat. As this was my first time doing any paint work, I tried to study up on good old Youtube to make this look as stock looking as possible.
At this point I have the final basecoat completed and ready for clearcoat. Cottenwood around the Seattle area is getting bad so it was a constant battle to keep it away from the lip as each coat was drying. Fans and cans of compressed air for the resuce.
Clear coat applied, wet sanded, and quick polish completed (above). I wanted to polish more but had to stop because the color shade difference was just too much for me. If you don't notice, the lip is much darker than the trunk. Either my cars natural color has faded or it was was the primer being more of a dark gray vs the stock is more of a white. I left the lip out in the sun for a few days to see if it would help but sadly no change. From everyone I talked with, I would likely need to get a custom shade of blue to match my already faded color on the S4. As this was really a project I wanted to keep under $100 and I wanted to get this done before the Leavenworth Drive I decided I was going to go with stock Audi "Brilliant Black" color for my second attempt. Much cheaper then getting a custom color and it should be here in a few days. I've see a few other S4 with black colored lip and it looked pretty good.
In summary, I'm still pretty happy with my work as this was my first time doing any kind of automotive painting. I think the second attempt is likely going to look even better. Until then....
