I currently have two meteor cameras running. One has a 6mm lens enclosed in a conventional CCTV housing with a glass window mounted at 45 degrees from vertical. The second camera is mounted vertically under a clear Perspex dome. There's a heater and fan mounted inside the dome, so condensation clears quite quickly. However, rain drops can take an hour or two to clear from the outside.
I know that there are various products one can apply to plastics (such as motorcycle visors) to repel water droplets.
Has anyone tried these on a clear dome? I have two concerns: 1 - is the application process likely to cause micro-scratches on the dome? 2 - does the coating introduce optical distortion?
I'm loathed to try some without getting as much info as I can first for fear of trashing the dome.
Any information or experience greatly appreciated.
Thanks

Michael, I've used something similar but not on domes but on my windscreen, it works ok but I found that it left a film on the windscreen like if you washed your screen with soapy water and you didn't rinse it off looked horrible when the sun caught it, but the one I used was a clear liquid, maybe there's better products out there

I used RainX from my local Halfords on my dome without any detrimental effects. Just need to use a very soft cloth. I have changed the dome back to flat glass plate and still use RainX. It does seem to need regular applications if I physically dry the glass with a cloth after it has rained. Its not perfect, but it seems to help for a while. My cams are pretty vertical so water doesn't slide off as I would like, but its not a big deal to wipe it now and again.

Late reply , but yes RainX on a dome would work just fine.
