As far as finish goes, some people use different products. I use a latex sealer, which feels completely different than most finishes people use. Latex actually soaks in to the wood. I use a 3 part system for polishing after I put the latex sealer . 300 grit 600 grit 1200 grit and a micro mesh 2000 grit in some cases depending on how well I am compensated, but the 2000 is like $5 a sheet and you can use it like once and a half.
If you want a tip put on Im all for, I would like to get the cost of a tip and $10 for the labor. Ill refinish for that price for a penny.
