Dear K.Jirawat,
Thank you for your mail.
Regarding fin coating during maintenance this time, could you confirm us below issue
1. What kind of coating material will you use, same as in attached file ?
2. How long is hydrophobic performance after coating ? How to confirm hydrophobic performance still good ?
In maintenance schedule is every 6 month re-coating, is it correct ?
Please confirm.
Best regards,
