Round 2

Reviewer 1 Report

Comments and Suggestions for Authors

The authors have addressed all the comments made in the previous review and the article has improved considerably.

However, some minor comments remain:

In the caption to Figure 2, there is an error in the application of the brush (b) and spray (c) coating.

There should be an error on page 10 line 414 where the authors say "The images, provide a visual comparison 414 between the uncoated sample (Figure 6a), the coated sample (Figure 6b), and the coated samples 415 after accelerated aging (Figure 6c)" talking about the contact angle measurements, but in this figure, the coated samples are shown during accelerated aging. 

Can the white material in figure 8 after STT be attributed to the salts formed during ageing or to the coating? A comment on the effect of the coating application procedure on the formation of salts would be interesting.
