I know you don't wanna hear this, but...

Can you take it back apart and paint the components with longer, flowing strokes?
This usually leads to much more even coats, and you can use a wider brush to minimize stroking. 2" is kinda on the skinny side to be painting ASSEMBLED shelves....lotsa strokes to cover that area.

>>> Brushing an assembled piece is tricky, unless you do it every day. Spraying could be an option, BUT you've gotta be used to a good technique!

Variation in sheen:
* Usually due to too much paint in some areas vs. others...AND/OR some remaining substrate porosity, meaning primecoat too thin/sanded away slightly too much.
* With those kind of woods, I'd prime TWICE, mainly to give slightly more "sanding cushion".
* Then lightly sand the 2 primecoats.

Bottom line:
IMO...take it apart.
* Since you've largely sanded everything again, I'd apply 2 more evenly/long-stroked Cab-coats with a wider brush.
* 30 seconds is "Red-alert" brushing time! Try not to go past 1 minute.
* Lay on a nice even coat...then get away & repeat next day.
* I'd wait a few days b4 re-assembly. Then I'd put it aside FOR A MONTH b4 putting things on the shelf....I'm serious here!

Hi Faron -- thanks for the reply. Unfortunately disassembling is not an option -- it is built-in and has been completely fastened to the wall (plus the top/bottom/center shelf were dado'd and glued with screws). I do believe I could have primed more thoroughly -- some areas, especially those that were rolled probably didn't get enough primer. So, besides using a wider brush, is there a painting technique/method you would reco that would allow me to achieve a higher quality, more uniform finish? I am content to go slow, and get it right. What about something crazy like taping off the shelf bottom and top and painting just the sides and back one day, then removing tape and taping off the sides/back and painting the top and bottom??? Or, should I consider using a different product. I was so excited about the Cabinet Coat given the amazing reviews and the fact that this corner bookcase will be a real workhorse in the kitchen (holding phone, cook books, kids school info, etc -- along with some decorative pieces). But, maybe I should use something that doesn't have such a short dry time? I've already invested the almost $50 in the CabCoast, so I'd like to give it a shot, but I am a realist and wondering if I will be able to achieve a nice finish. Finally, one last question, let's take an example of painting a vertical 45"H x 20"W section (ie. the shelf back) --- if I start painting at the top and I am moving left to right, should I take a single brush width all the way from top to the bottom before moving tot he right? I have to admit, I am kind of confused by the description of "painting from dry into wet areas" -- I don't want to make this harder than it is, but haven't had great results so far, so ready to give it another shot the proper way!

This is really a perfect example of modern day painting. The fast dry times make brushing out large flat areas very difficult and this is even more true for a novice painter. One of the reasons that the crown and trim pieces may have come out better is because it is much easier to keep a wet edge there because it is narrow and simple to paint from one end to the other without overbrushing or going back into areas that have already started to set. For the big flat areas, I would use a roller. After you roll a section out you can always backbrush it or just leave it. Some paints will flatten out on their own if you just roll it and leave it and some paints will need to be brushed out to look best. Try rolling out a sample board first and see how it dries down. Doing it this way is really the only option with fast drying acrylics because we waste too much time going back and forth to the can dipping our brush. Even if you backbrush, the rolling is just used as a method to get the paint on faster.

Stay with the CC!

2 more coats on the horizontals (since that's where the wear is!)...maybe 1 more coat on verticals, since these can be thinner coats anyway to prevent sagging.

Sectioning:
* Yeah, you don't have much choice now since it's all installed. Take out any removeable shelves.
* Save all horizontals/crowns/other "outside" trims until last. Use some rosin-paper/similiar to cover fixed-horizontals.
* Practice your technique/rolling/stroking with the actual equipment, but no paint. Consider placements of your trays, etc. too.
* As PG says, rolling-then-immediately-backbrushing gets these types of paint on faster.
* Have the room on the cool side if you can.

Dry-into-wet painting:
* Picture a 4' wide x 18" deep shelf.
* Start @ the far left and evenly stroke the first 2'.
* Now...@ the far RIGHT, apply paint unloading towards the center.
* This way, you don't keep trying to spread a load of paint from left-to-right. It ends up being more "plowed-along" if you keep trying to push the same "pile" of paint!
* Then do long/light smoothing strokes across the whole top.

Again...it's gonna be a month b4 I'd put stuff on the shelves!!
