Calyx is so easy to use as a touch up that it is not an issue for me at all. You can reach everywhere that matters leaning over the fender. It lasts a lot longer if you keep the truck out of the weather.
I have read many positive results, but it does say that reapplying is necessary. When I yank the engine I will be forced to make the decision to ceramic coat or use this. I am still in the mode of finding ways to not have to work on the truck once done.
Ha ha ha ha. What a oxymoron I just made.
