Also when sanding, change the direction you rub when moving from one grit to the next. i.e Sand lengthways on 220 until all the 80 grit scratches are removed then sand widthways at 400 until all the 220 grit scratches are removed.
You might also have to compromise on just how perfect a finish you're going to be able to get, depending on how big a restoration job it is.
