Do I need a separate strop for each different level of grit or can I remove excess compound with a credit card and apply the next level?

We believe a careful cleaning with a straight edge like a credit card will be sufficient in between pastes.

Which to use on a garmen forerunner 235 i believe its acrylic face?

This is for glass. Use polywatch for acrylic.

Which micron size would you recommend for polishing medium scratches in sapphire / hardlex watch crystals? So far, my 3.5micron stuff isn't cutting it

If the scratches are still present after using 3.5 micron paste, then you would need to go to a bigger size. You can try the 5 micron paste and work back down.

Can you use on plastic? I want to use this for modeling pieces.

This page covers 14 different grit sizes. I think that the grit size would have a very significant bearing on whether or not a polishing-paste could be used on model plastic (I'm assuming you mean model plastic as in, common commercially-available models). Without knowing which grit you're looking at, I don't know that your question can really be answered. Sadly, it's been years since I did anything with models, but I do remember that the best results came from using the finest grit possible - but I was also using sanding film, not lapidary paste. - I think that Richard Thien's advice is the best.
