Yeah this is incorrect. Just one example but I had ceramic coating on my RS (done by a detailer) and since it was stored in a garage the ceramic was still in great shape after 5 years. For our outdoor/street parked cars I've seen ceramic last at least 2-3 years with regular maintenance.

Big difference of course between a spray on product one can use at home versus having a professional detailer do a full paint correction + ceramic coating.

 

Yeah that has been my experience as well, which wasthe reason for my question.

 

If you have ceramic coating, wash car by hand or with touchless car wash. Brush car washes degrade the coating.

 

Mine was done by a detailer in 2019 - daily driver, garage stored. It still looks very clean when washed (by hand or touchless), but I feel it is time to re-apply.
Thanks!

 

If it isn't beading as much as before you could try either something like CarPro Reload or get your detailer to do a maintenance wash + ceramic refresh... on the latter, apparently using a high PH soap along with a product similar to Reload will help 'recharge' your coating to get some more life out of it.

Depends of course on what coating was used and the condition... 5+ years of life is pretty good though. If you go the reapplication path definitely get the paint corrected as part of the process.
