Re-finishing a hardwood staircase

[Pricey]

I will be helping my mate re-finish his spotteg gum staircase and was wondering if anybody had some tips.
They were originally sealed with a clear lacquer, not sure what brand.

I was wondering what brand of finish would people recommend?

Also what is the easiest way to determine the type of existing finish, water based or thinners. I will be looking to lightly sand the existing finish and coat over it as there is no signs of flaking or anything of that nature.

Any advice would be appreciated.

Select an area that is not too visible and wipe with GP thinners on a cloth. If it comes off, it is an NC based lacquer.

I think you will find that if you are rubbing back the finish anyway that the base coat shouldn't matter much.
