Tentative final gear list:
- liquid wax
- combo nylon-cork or nylon-felt brush
I am getting the vibe that there are mixed priorities here that keep pulling you one way then the other into rabbit holes for perfeftion. Like why are you planning to spend hundreds of dollars to get truebars and basebevel meters, but at the same time you don't have a brush kit yet? What are you going to do with that data when it says your base is varying in spots to 1.2degrees, or you got some light peeking under the truebar in your shovel?
I think take a step back and value time and money, rather than getting sucked into pursing perfection.
Anyway for the liquid wax, you should look up the application instructions for the specific product you intend to try.
You don't necessarily need to pile up with specialized corks and brushes, unless you have unlimited budget.
If you're looking to use the toko spray, they have a starter kit that includes the brush, so I would suggest that if you are going toko.
For holmenkol liquid they suggest to just wipe on with their "carefleece", then polish with felt cork, but you can get to the same result with a shop towel and a soft brush(if you have no brushes). And you don't need to spend $30 for a special brush for liquid wax that you are applying in the parking lot, you can find something at Home Depot for $5.
