No, don't use that stuff.
Check the clearances.
It is likely sticky because the clearance it too tight.
You have to scrape/shave the channel until it can easily move.
Sometimes there is very little clearance to get something into the channel, to scrape it.
And do this to the HOOD, not the lens.
I would try the wax before I would scrape the grooves. A little lube is all that's necessary and you don't want to make the hood too loose by overdoing the scraping/shaving. As it is now after the wax treatment, it slides easily but holds its position retracted or extended firmly. I bought the JJC hood almost four years ago and it's still working fine after the first treatment. No scraping done.
