GF recommends a MINIMUM of 3 coats.

It says right on the can “Three coats are recommended”.

I ve used a lot of different finishes in a lot of different ways through the years. One thing I have learned is adding more coats than recommended usually ends with a headache!

Um, yes, RECOMMENDED, not required as I wrote. Well documented on the label AND in literature available from GF on their web site or sales displays. Information found in the SDS and technical data sheets will be more in-depth than what can be found on the side of a can.

The word “minimum” appears in the further documentation. Due to variation in application method/technique/thinning, etc. they are allowing for the possibility that an additional coat may be needed to reach a total finished 3mil thickness (3 coats of 1mil each, the 1mil coming from the coverage recommendations found in the technical documents).

There are no guarantees of success implied by GF in their instructions. They are in the business of selling finish. Success is implied to come from three coats but they (or any manufacturer) is happy to sell you an extra can so you can get four.
