I used to own a Smart4Two Passion Cabrio in red that did the same thing. The panels were made of red plastic, so no paint involved. But the clear coat started peeling off in spots.
I talked to several body shops about options to re-spray the clear coat, and as others here have confirmed too? The cost was prohibitive. The big problem is all the labor involved in the prep work to strip the old clear off, sand/polish the plastic panels and ready them to re-spray with new clear coat. One shop did say they'd probably discount the job about $1,000 if I took the panels off the car for them first and brought them in to be sprayed separately.
I wound up buying a replacement red tailgate panel that was "new old stock", from Smart Madness in TX. (It wasn't a part shown on their web site but I called and talked to them, and they managed to track it down for me. Took a long time to ship out but I finally got it.). I was able to take off the old panel and put on the new one after watching a few relevant YouTube videos. The other panels that started peeling on me were the rocker panels below the doors, peeling right along their edges. I wound up trading the car in before I got around to replacing those.
The interesting thing with these cars is, with the removable body panels like they used? Nothing is stopping you from changing the color of your car if you want to replace all of them. Some people have even done a "mix and match" thing to create a unique 2 tone look for their Smart. The biggest challenge can be finding the panels you need in the color you want. I know with red, especially, it was a panel that had a lot of problems with failing/peeling clear coat, even when the cars still had warranty left on them. Mercedes/Smart replaced them for some people, for a while, at no charge. But these days, the remaining stock is just whatever is left in inventory, or people reselling used panels still in good condition. (Some are on eBay here and there.)
I have a 2008 smartcar that’s peeling, like sunburned skin. It’s losing color in spots, and I was quoted around $4,000 for some sort of paintjob over all of it, I suppose.
Does anyone have experience and advice for this problem without my having to lose an arm and a foot?
I’m not trying to restore it, just to make it look nice. I love the bright yellow original color, and hope to keep that look. Can’t imagine doing it myself.
Would it be wise enough, to have it spray-painted, or must I go for the wrapping material that’s sure to start peeling again?
Thanks in advance for your sound advice. Ruben
