Does anyone know of any incompatibility with sanding sealer? I'm doing
a repaint and stripped the cabinet down to bare wood. this time i'm
not going to prime the cabinet but seal it with minwax sanding sealer.
Is there any paint ie krylon or rustoleum that has a problem with
adhesion. I know the manufacture never primed before painting but what
did they do to stop the paint from being sucked up by the wood.

The Minwax site suggests their product is use with a polyurethane
topcoat. There is no mention of enamels though. IMHO, I would be
reluctant to use it with Krylon or Rustoleum spray bombs. Enamel and
acrylic urethanes don't get along, IIRC.

I've seen other posts were people used sanding sealer, what paint are
they using? or what type of sanding sealer?
or should i just prime white paint or base coat over bare wood?

I haven't repainted a cab yet, but when I do, I would use primer
spec'd by the paint I was using.

I'm not sure if it matters but it's the pro formula for oil or water
base top coats.
I search in web and couldn't find an answer so i'll have to make a
test piece of wood and seal it sand it then put a coat for the top
coat and see if it works

I would use a primer made by the same company you are painting the top
coat with. Any oil based primer could give you big problems, unless
you are planning on using an oil based top coat. But I could be wrong.

this is the project, i have a black hole that was complete except was
missing the cabinet. I have a MGOW cabinet that i stripped down to
wood to replace the missing BH. I will use rustoleum painters choice
blue to base coat the cabinet.
should i just spray the wood with the blue? I know many people have
restored BH in the past did anyone prime the cabinet or just spray on
clean wood?

one other thing, rustoleum makes Varathane and they have a sanding
sealer is that any better combo with painters choice spray paint

On an unrelated note, you may have to fill the shooter rod housing
square cut out on the MGOW cab. BH does not have that cut out.

I would prime the cabinet first. That way you can still straighten
out imperfections in the wood before the final coat. Plus, the primer
will allow the finished coats to bond to the wood better.

I'm not sure i understand you shooter rod issue, are you talking about
the hole shape or the surface being angled slightly?

There seems to be alot of confusion on the proper steps to use when
painting cabinets. At Big Time Cabinets we used (and/or experimented
with) a variety of coatings including lacquers, oil based enamels, and
latex. Some comments:

1) First and foremost - there is a general impression that the wood
will "suck up" the paint. This is true BUT the amount of paint that is
"sucked up" is minimal, because the porosity of the wood (usually
pine) is really not at all like a sponge. A base coat of paint that is
applied and dries is sufficient in itself to act as a "sealer/barrier"
to the final coat. No need for special primers, sander sealers, etc.
If you want to, you can, but there is no need - the wood is very
porous and will adhere the paint.

2) When using paints be sure that the product(s) you use are from the
same manufacturer, to disallow incompatibility problems.

3) Filling with primer to sand and get a smoother surface is really
only necessary if you are trying to get an appearance "beyond" factory
finish. This is especially true with stencil jobs (like Black Hole).
Primer is wasted otherwise.

4) My take on paints:

a) Lacquer - flows well, dries quickly, sands easily, repairs
easily, hard to find because of EPA regulations. Two coat minimum on a
wood surface (tends to be absorbed more because it is a very low
viscosity paint, and color consistency can be tricky).

b) Enamels - flow well, dry slower (get more "tacky"), not easy to
sand, easy to find. Don't get absorbed as quickly, best for ACCENT
colors, NOT base colors. Avoid oil-based enamels, they take FOREVER to
dry.

c) Latexes - flow well, dry reasonably fast, sandable only with a
"wet" method, readily available. Being water based, they do get
absorbed but again, two coats are usually adequate as the first coat
seals the wood. High viscosity, good color consistency, very safe,
water cleanup).

Good luck!

The surface around the shooter housing is "notched". You will see a
faint square around the shooter housing, which changes the angle of
the shooter rod.

I squared that off during the cabinet repair and sanding, I never
noticed that on any other machine. was that the only one with the
offset/angled shooter rod?

Thanks for the help I think i'll just shoot the base coat on raw wood
and just do an extra coat if needed.
