Update: Singapore Selffix DIY is selling this 🙂 (Thanks to reader)
You will never get wet again with NeverWet spray. It may sounds like a sales pitch but when you see the video, I am sure you will be like me. This Rust-Oleum NeverWet is a spray that basically waterproofs everything. From shirt to devices. Check out this video.
Not sure how long the effect will last but the demo is very convincing. Check it out.
I think the nearest from Singapore is Hong Kong if you are interested.
