I use solvol autosol as a final polish to both piston and cylinder, but never with the piston in the cylinder. That is simply a recipe for failure; the only thing that should come between a piston and a cylinder is oil. Trust me, I have in excess of 50 engine builds behind me of more than 40 different designs.
I have never had trouble to lap the piston straight into the cylinder and compression is still good as before for several years in my model engines. The method I learned from Jan David-Andersen (model engine maker who produced these D-A engines) when I received the book about model engine construction authored by Jan David-Andersen. The main problem is that there is no practical training of younger generations to lap the piston / cylinder and lap the piston into the cylinder.
