Well mine still works.
I used the aerosol because it's the only one I could get in my country (cost me about 16€)
I did run in snow (wet and powder) and it was covered in it but no problems. Also ran stock the day before (not sprayed yet) and it survived but started to cog once and some smoke came out. Maybe it was the fan.
