I never got around to finishing a piece. I had about 3 coats on it, but was planning on 4 coats of water based poly (brush on). It's been months.

So, is it reasonable to expect that I can rough it up a bit and apply the last coat ?

Just do a scuff sand with 320x. You might like using an open coat sandpaper. It's a light grey silicone carbide intended to be used dry. It could be called 'No-Fil' or 'Fre-Cut'.

I use a Accuspray three-stage turbine rig; the result comes out better than brush painting and I never had a problem with waiting quite a bit between coats, in fact I think it comes out pretty good when I do. Just make sure that the surface is totally smooth so the result is polished.

I am not sure about brushing but I guess there shouldn't be a big difference
