Weather, heat, and garages have been discussed as possible causes of deteriorating membranes, but what about the actual water that pours onto them? Do you folks use detergents (car shampoo, foam, etc) when washing the car? I usually use only water (nothing fancy, just tap water out of a garden hose) and foam maybe 2-3 times a year, and do not have any cracks yet.
 
Interesting. I was working under the hood of my 2024 Emira, and the dealer installed water membrane was already crumbling in several places. I don't know what kind of rubber they used, but it's rubbish. I wonder if it's possible to seal the fuse box instead.
Not sure I am 100% right on this, BUT, I think the membrane protects more than just the fuse box.
Cant remember what else, so I could be wrong

The resistor pack on the air con unit is the other component affected by water ingress that `bib` covers.
 
I'd love to, but figuring out shipping world-wide and setting up sane shipping pricing is a pain.
Still looking how I can get that going
With the amount of people interested, maybe @GRP could give you a hand with the distribution process?

I feel like doing the R&D and figuring out which specs membrane is the best and adding it to the GRP website would be a great way for us international folks to buy it.
Right now it looks like every Emira will need at least one replacement during their lifetime, and we are about 50+ people interested right now in a membrane.

If it was on the GRP website, I would buy it in my next order 100%.
 
I figured out how to setup shipping and currently checking import taxes paid so you get DDP to your door.
Now setting up a rudimentary product page and we're good to go :)

I was just told from a lotus mechanic that the membrane they install breaks down after 6 months. I opened my hood and they didn’t even install it. Luckily my car is covered so check yours soon so the electrical gremlins don’t get you!

You have to try hard to find such junk. Maybe it’s the heat in the area which accelerates it, but it’s crap. I wonder if, in the days of 3D printing, we can make watertight enclosures for the sensitive parts
 



Start at 9 minutes for the membrane install.
We should just by it ourselves and to cut it like he did. But where did he buy it from and what is the thickness??
 
I used this from Home Depot and holding up well so far…
EPDM 1/16 in. x 36 in. x 72 in. Commercial Grade 60A Rubber Sheet - Black
Used a bit of shin etsu to slide around the bars better

Do you have any pictures? Was it easier to cut than the one shown in the video?
