Jim, I have resorted to using VCT stripper, doing three applications. Then the (water based) finish still fisheyed in spots, so I let it dry and cut it back with acetone.
Any recurring fisheyes I hand scrubbed with fine screen paper, then wiped with acetone, spot coated and it all sort of blended in the subsequent coat. I have no idea if this was all the way to do thigs, but used what I had on the van and got lucky.
I also strip it with a commercial floor stripper, nothing else will touch it. One of the experts on here had an explanation about how the polymer links in commercial finish work and an explanation of Orange Glow etc. are a much different type of product. Tell the customer you can't guarantee anything but the floors I've worked on came out OK. Charge out the ying-yang as it's nasty work in a residential setting.
Dangerous place to blindly charge in without knowing:
1. What KIND of wood?
2. What KIND of construction?
3. What original/added FINISH?
I've got a scheduled project with 5k' of engineered distressed hickory fused hardwood, with UV cured metal linked urethane coating. Exotic, beautiful floor!
