I use a UV protectant spray on mine after every wash - i think the clear-coat on the CF is somewhat susceptible to UV and chemical (bird-dropping) damage. So far no damage to mine. I use Wolfgang Concours Series WG-9200 Deep Gloss Spritz SealantI am very vigilant about keeping my car clean yet I have already had the finish eaten into in two spots. I now put a cost of spray wax on it every time I wash.
I removed the silver chrome vinyl film from the roof of our i3 today. If I had had an infrared thermometer and there were no COVID-19 restrictions, I would have parked our i3 with its reflective roof and a stock i3 in the noontime summer sun and measured the temperatures of each i3's headliners after being parked in the sun for various periods. That would have quantified the temperature difference. However, it didn't happen, so I'm left with only a subjective feeling that I could feel less heat radiating down into the cabin after wrapping the roof with reflective film.alohart wrote: ↑Mon Oct 19, 2020 11:36 amInstead, I bought some inexpensive silver chrome vinyl film to install myself. I had hoped that the roof was flat enough that I would not have to heat and stretch a large piece of vinyl film to avoid wrinkles along the edges. Unfortunately, that wasn't the case, so my installation looks terrible. However, it does reduce cabin heating noticeably when strong sunlight shines on the roof. I will probably remove the film as winter approaches, but probably won't pay to have it wrapped professionally because our i3 isn't driven much (only ~11k miles in 6 years) and is parked out of the sun in our apartment parking garage.
You can find it discounted, but yes, it was not inexpensive, but what from BMW is 'cheap'? My experience is that it keeps the interior probably 20-30 degrees cooler when on, and, with the large front windscreen, those take up a lot of space when you store them.
Yeah, If my car sat in an open parking lot all day, totally worth the investment, but with a shaded driveway, and only an hour a day at the gym where the car sits in the sun, my accordion fold inside window screen does the job.My experience is that it keeps the interior probably 20-30 degrees cooler when on,

Our smart sat in the sun in our driveway not 4 miles away for the same time and it was cooled off in the 15 minutes it took to drive there. Ditto our Infiniti...... To me that indicates that the a/c could use some help.MikeS wrote:What makes you think the a/c is marginal? Mine works as well as the ones in my other cars.
BTW, this is typical summer heat where I live, not every single day, but quite common nonetheless. A car designed for city use, ie running errands ought to be able to cool the vehicle between stops and shops. Perhaps they should have Northern and Southern versions?
Maybe when charge points are more widespread people will just keep the a/c running in Precondition mode when parked and plugged in. That way the car would be cool when they came out and that way they could waste more energy than an ICE defeating the purpose of going EV. And why not when power is often free.....?
