Anyone notice if your ceramic coating is fighting off bird bomb etching better than sealant/ wax combo. I noticed a bird bomb(been there 8 hours, car in sun but only 55F) on our IS350 that was coated with Gtech EXO ultra v4. It cleaned up without any staining or etching (coating was 5 months old , topped 1x per month with sio2 spray). Compared to my other vehicle that was sealant coated followed by wax topper which had stains n took some work to fix (cleaned up and reloaded)(sealant n wax only a few months old). I am sure it depends what sealant/ wax was used.

Any info on what you have noticed would be useful ( I am new to this detailing process, 6 months). Followed Mike P’ advice to at least remove the bird bombs, worked great.
