I've now had my detachable pedals detach themselves twice. The first time was immediately after I'd been demonstrating how the pedals worked to some friends so I put it down to user error re-attaching them. However, the second time occurred after a few weeks of riding without detaching the pedals.
Both times the pedal came off as I stopped once whilst I was still moving and once just after I'd got off the bike. As I said before I never had trouble with the pedals on my Dahon, and coupled with when they came off I think it may be the twisting to get out of my Power Grips that does it.
Of course that shouldn't be enough as you have to twist the collar as well as push it in, but close inspection reveals that the twisting spring only pushes the collar a few millimetres away from the crucial point, you can twist it a full 90 degrees away manually though. Any rubbing between the shoe and the collar during forward pedalling should actually help to secure the pedals, so I guess that I must have back-pedalled and then twisted my foot out to cause the pedal to detach.
At the very least I'm to have to be a bit more careful from now on. I am even considering sending the pedals back and getting some non "superior" ones that will be a bit more of a hassle to take off, but won't come off by accident (due to the plastic locking ring). I'll wait and see what my new commute is like and how often I'll need to take the pedal off.

Brompton Stickers and Paint
As I mentioned in my rather long and rambling initial thoughts, the orange paint on my Brompton doesn't seem to be very hard wearing. Looking over the bike recently I noticed that the front brake cable had already managed to rub through the paint on the fork and was getting close to doing the same on the main frame tube.
Coupled with the paint chips I reported on initially I decided it was time to get some touch up paint and see what it could do. So I bought some matt Brompton paint from SJS cycles. As the cable rubbing was only going to get worse with time I also bought some protective stickers at the same time (I found it surprisingly hard to find bicycle stickers that weren't either branded or reflective).
Before painting I cleaned the chipped and worn areas with a little white spirits. Applying the paint was fairly easy, there is a small brush in the lid (like a nail varnish brush). The only thing to be careful is to wipe the excess paint off the brush before starting.
The paint dries fairly quickly, and, once dried, is a fairly good colour match (at least on my frame) but not identical. You can see the colour difference here, along with the fact that it's doing a better (but not perfect) job of standing up to the pressure on the inside of the joint.
Once the paint was dry I applied protective stickers wherever there were signs of rubbing. As some areas only had light marks so I didn't re-paint them but still stickered them. The main areas were where the cables touch the frame and forks and where the front wheel hooks over the rear triangle when folding.
With my new brake levers there were also signs of wear where the cables rub on the other side of the front fork when the handlebars are folded. Finally I stuck one sticker under the chain to protect the frame from all the grease that comes off there.
I'm fairly pleased with the results. The stickers are fairly thick and so should provide good protection - as long as they stay put. So far one has slipped out of position but I do at least have plenty of spares in the original pack.
