Probably the most weak point of the easy hood is the rear contact to the side window frame. The round reinforcement must remain flexible for folding the hood. Hence, it does not seal sufficiently and also causes aerodynamic noise (see photos).





A piece of plastic edge protection (or similar) imposed provides the necessary stiffness.









However, for folding the hood, the plastics must be removed.

Another point are the "donkey's ears" at the front (see photo) - unaesthetic, causing noise and probably also letting more rain inside than necessary.



Two bonded strong neodyme magnets keep the hood edges in their place. Opening the door, they easy "slide" by side. However, after entering the car, the magnets must be joined manually.

Looks very neat....

Up to what speeds do the magnets hold? I'm only asking for +8 owners.

Very clever indeed. What strength neo magnets did you use, I’d like follow your lead

So far, the magnets hold at approx 110kmh. It also depends on wind conditions. I chose these magnet size also considering the aesthetics, as I didn't want to have there to big magnets. Might be, they will not hold at very high speeds. I am still experimenting, didn't try higher speeds. On the other hand, when raining, I seldom drive at high speeds.
The quadratic magnet is 5x5x5mm and holds around 1,5kg. The round one has a diameter of 10mm and holds also around 1,5kg. The bond I used is a 2K Bison Power Polyurethane Bond, as it is more elastic. Probably any epoxy bond will do.

If You are following with the plastic "stiffeners" described above, avoid any sharp edges, not to hurt the synthetic leather when imposing it. A bit silicone smear will facilitate it. Round both ends and inner edges.

Just tried higher speeds - the magnets are to weak for speeds higher than 110kmh. In some places there was a strong wind, they then did not keep even around 100kmh. So, the magnets should be stronger. However, they will be larger.

Try driving with the hood down you won't need any magnets rofl
