Why don't you just start off with the lightest polish and pad you have and work your way up until you find the right combination of polish and pad that will work? Then report back to us and let us know.

Especially if nobody can tell you the hardness/softness of the paint.

IMO, I wouldn't just ask and then go to town. I couldn't trust someone to just tell me how the paint is anyway. I have to get a feel for it myself. Their opinion of soft and hard might be way different then yours. Checking the paint hardness by moving up in polishes and pads is always the safest way.
