Optics coatings are more robust than people think.
But Aeroguard will strip them. NEVER spray aerosols anywhere near a scope!
Pete (exfso) had $5000 damage done to his Takahashi when it picked up stray Aeroguard spray at Camp 2 years ago. The Aeroguard actually ate into the glass!!!
The scope had to go back to Japan to have it's primary lens replaced. $5000 plus freight both ways.
BEWARE of aerosols!
