I guess the term “coating” is a matter of semantics.
Although I don’t have one of the new Canons, the very good review on the On Site website suggests that if you choose the appropriate media setting for a particular paper type ( this is critical ) the gloss enhancer channel does a quite good job of removing gloss differential and bronzing issues.
I know on my HpZ printers the GE channel does an excellent job in smoothing out these effects on all the fiber gloss media and an even better job on rc media. I would hope that the Canon GO would do the same. Since I’m using an older Canon I can’t say for certain. I know my 8300 produces results that are about the same as Epson output.
Having said all that, for portfolio prints that are to be held in the hands I almost always add an additional two light coats of the Premiere Art solvent spray, especially for black and white. It also makes them more durable. So there is an additional improvement with papers like Platine or Canson Baryta even with the HP Z inks.

I print on the Pro-4000 also. It just dawned on me that I may not have to spray a Solvent based liquid laminate protective coat 1st. Some papers bleed if you apply an aqueous based coating 1st. The solvent based laminate will stop the bleeding and once it sets you can then spray the aqueous based protective coating directly onto the print. If the CO can act as the 1st layer in place of the solvent base laminate to prevent bleeding that saves a lot of time/work and is very efficient. I would only have to spray once. That would eliminate an entire application step along with having to clean the spray gun plus reduce the likelihood of dust contamination. Sweet.....
tharrington, thank you for your input. Why didn't I think of this 2 years ago?
