Many ways to skin this cat. 

I was thinking this could serve as “skin in the game” and maybe lesson the 20% down payment required.

The more comfortable you become in your own skin, the better.   

There's always more than one way to skin a cat, my takeaway for @Zane Lyons is be sure (for any contractor/trade) you know how they plan on doing work, not just what they are doing.

I totally understand the value of "putting skin in the game" so to speak.

A contactor is a business owner and has skin in the game.

I start to suspect that lotion or natural skin oils can disolve the finish if you are barefoot a lot.

I use Surface Solutions in Canton, MI for instance.

Regulations/requirements may vary by location and this doesn't constitute professional advice: I've helped remediate a couple buildings and IMO the best solution is to toss all porous things and thoroughly clean all hard surfaces.
