The valve cover was filthy, covered in grease and flaking paint. After trying several degreasers we had, the one that worked best by far was POR-15 cleaner degreaser diluted in water. Here's what it looked like after a thorough degreasing and removing the worst of the loose, flaking red paint:

I scraped the rest of the paint off with a razor blade...

...sanded it to smooth out the surface and get rid of surface rust and oxidation, prepped the surface for painting by giving it one last cleaning and wipe down with isopropyl alcohol...

... and masked the edges and stuffed the holes that I did not want to get over spray on.

After the first coat with VHT Wrinkle Plus high temperature black spray paint:

I followed the instructions to do 3 coats in different directions: one vertical, one horizontal, and one diagonal. After the third coat, you could start to see the crinkling effect. I left it to dry until the next day, then hit it with a heat gun for a while to help cure the paint. The texture wasn't completely even (there were still a couple of shiny spots) but I thought it wasn't too bad for my first attempt.

And finally, sanding the bars and the lettering. The paint gummed up the sandpaper quickly, so I found it was easiest to scrape as much as I could off with a razor blade first and then sand. There were some deep gouges that needed a coarser grit to smooth out, and then I used a sanding block with a finer grit of sandpaper to get the final brushed finish. I was worried about sanding off the new black paint, so the areas around where I was sanding got taped up.

That turned out to be a huge mistake. When I pulled off the painter's tape, layers of the new black paint came off with it. I thought that the paint was already cured and hardened by that point. I was wrong.
Oh, and "touching up" the spots that peeled off with additional spray paint didn't work. I tried. It seems that once the paint has dried you are SOL and stuck with it as is.
Now that it had turned into a huge mess, I decided to start over and give it another try. The part with the lettering looked awesome, and I loved the black crinkle effect, but I must have gone wrong somewhere along the way. I think that the biggest mistake I made was leaving too much time in between coats, which probably allowed the paint to dry too much in between and not adhere in between the layers.
On the bright side, I now had a chance to try out using aluminum paint stripper, which would have made the job easier in the first place. I was looking for aircraft paint stripper but couldn't find it for sale anywhere locally. I ended up using MEK (Methyl ethyl ketone), which removes paint from aluminum, though it will eat through plastic. The paint started to bubble off as soon as it was applied.

Most of the paint scraped off easily with a razor blade or wiped off with a rag after it had been saturated with MEK. One benefit of my "workshop" being outside (no garage) is avoiding fumes from stuff like that. Somehow, it looks like I've managed to completely avoid the sun as well. ;)

Once all of the paint was off again, I went through the same drill as before: quick sanding, paint prep and masking. I did three coats of paint plus a bit extra at the end anywhere that looked like it needed it to make sure it would crinkle, and actually set a timer for 5 minutes in between coats this time.

The second I sprayed the first line of paint, it started raining and I had to relocate to my front porch to finish painting. I used the heat gun on the fresh paint as soon as it stopped raining - otherwise it might not have even dried properly due to the humidity. By then, it was late and I was working on the lawn in the dark with a flashlight, feeling like a real professional!
The paint on the valve cover started to crinkle up evenly, so I think it's going to look great. I'm going to leave it for a couple of days before removing the tape just to be safe this time!







I’m starting to get a bit nervous about whether I will even get it back in time for 


(EDIT: It turns out that my partner turned eco mode on on purpose to save fuel. One mystery solved! Sadly, however, turning eco mode *off* does not perceptibly enhance the power delivery in any way.)


And, I believe they meant emergency brake.
