My Atto3 originally had silver colored C-pillar covers. I ordered a set of black covers that can be mounted on top of the existing ones. The result is shown in the added pictures. Mounting these covers is very easy because along the inside’s edges a strip of 2-sided tape is plcaed. . Just remove the cover tape a bit, plac ethe cover where it fits, and carefully tear the cover strip entirely off the inside. Press on and you’re done!
