Step away from the Cetol and nobody gets hurt.
hot coating cetol looks like crap and it wears poorly.
Taking days to apply cetol ensures the same result.
In my overblown and opinionated opinion, if you have so little time available and apparently so little concern for the wood on your pride and joy that you are not only using cetol but looking for ways to get it over with more quickly, just cut out the middleman and do nothing at all.
8-10 coats of proper as-Herreshoff-and-Stephens-and-Neptune intended varnish thinned and sanded as per a tried and tested schedule will take you 2-3 hours a day over 5-6 days, applying two thin coats a day for the first three days and a coat a day after that until you have 8 coats...
and you won't have to touch it for a couple of years.
You can invest 16-18 hours every other year to get results that make you proud or spend 6-8 hours a year, every year, just to get the job done.
I'd rather invest my time than spend it.
