Are you trying to avoid the polishing cloths? If so, you will need to use both the Tamiya products but my advice to you is, if you don't mind using the polishing cloths, start with 3200 and go up to 4000. After finishing with the 4000, all you would need to use is the Finish. The polishing cloths eliminate the orange peel and though the polishing compounds do the same, they do not do it as effectively as the cloths. After finishing with the compounds, you can add the decals as long as you don't put a wax coat on it.
