For wood it's my melamine method all the way in most cases for me, but that won't come as any surprise to most people.
For acrylics, to 1200 grit, them Liberon 0000 wire wool with the lathe stopped, then Chestnut burnishing cream with the lathe running.
[USER=2526]@Hallelujahal[/USER] , Alex, you need to omit the friction polish at your step 2. Friction polish is shellac based but it has a wax content, and wax is a very poor substrate for anything else at all on top of it, apart from more wax. By applying friction polish before you apply your step 3, you are seriously decreasing the ability of the CA or the melamine to bond to what it's supposed to be bonding to, which is the sanding sealer. You won't be building a better shine by applying it at step 2, you'll just be shortening the life of the finish on top of it because it will have a hugely reduced resilience.
