<html> Hi Wim,               One top to 8oz of acetone has worked for me.  I use much less saturation than 4:1 laquer and thinner.  Easy does it. Untill you get the feel for it.  Applying it with a wide Camel haired artist brush gives very good control.  Make allowances for significant brightning after 24hrs. Definitely a back against the wall treatment in my book.
