Iíve finally got around to spraying my Matte Black tank. Plasti-Dip Camo Tan. Pictures tell the whole story. I did have a couple of spots that needed smoothing from the first coat. This was easily done by dabbing with paint thinner glove handed and rubbing smooth. Peep my pics=)
I also did some Plasti dip painting at my Ducati in the past, but I guess you need to be very careful with fuel on it and don't clean with too much pressure and power!
Let us know about your long term experience!
If your plasti dip peels during a power wash, you didn't use enough coats. I just got new wheels for my car, but my previous ones had been plasti dipped for 3+ years without a single issue. I wash my car at least once a month. That's a lot of pressure washes.
So you can wash plasti dip normally a pressure washer without worrying. I would however pay mind to the bit about the gas.
