3M PPS H/O cup users - mixing ratio liner?

[DynaGlide]

For those of you using the 3M PPS with a H/O cup, such as for a Fuji gun, can you put the mixing ratio liner like 16091 outside of the disposable PPS liner that holds the paint and inside the H/O cup?

I'm confused by these liners they say they're disposable but I'm wondering if I'd only need one for my H/O cup. Put it in the cup, insert the paint liner, mix right there? Or would the pressurized cup mess up the liner.

I don't understand why Fuji doesn't print the mixing ratio right on the H/O cup like they do with the regular cups.

I have the older style on my Q4. Never used the calibrated scale but as you describe it yes it goes between the cup and paint liner.

I have the liners but have never used them. If I need to mix I do it outside of the cup.
The liners would go in the cup first then the disposable paint liner.

Place ratio card in cup, place liner in cup, mix. If you place the card in the liner you can’t read it with pigmented products. You’d have to remove the card prior to spraying, it could block the filter/lid.

They are reusable to a point. If you want it to last longer, a fix it to the inside of the cup with clear packaging tape.

Thanks guys. Sounds like something I may pick up. Right now I have to pour into a mixing cup then transfer it to the liner which means cleaning the mixing cup. Not a big deal but a step I'd like to eliminate.
