Hi all...I am new to this group and also new to woodworking. I have done
fairly well in my first few projects except for the finishing. I tend to
get a lot of heavy brush strokes no matter what i try. I am using olympic
polyuerethane. I have tried thinning it, dipping brush in thinner before
starting, I have a fairly expensive brush....hell i have even tried brand
new brushes, and i dont go over it with the brush.....i think i am using a
thin enough coat........can anyone please help or does anyone know a website
with good advice.....
Thanks in advance for any help
Dave
Have you tried foam brushes?
Can get them at almost any hardware place or via many online sources.

Thin the polyurethane 10-25% with some odorless mineral spirits. I
personally do not care for the smell of "odored" thinner. Use a foam brush.
You can work the poly into a lather on the wood if you like. The key is to
tip off the brushed poly before it starts "drying". Hold the brush at a 45
degree angle to the wood and gently drag it over the surface. About 99% of
the bubbles and brush marks will disappear. The remaining will disappear as
the coating levels. The extra solvent enables it to level better than
straight out of the can. Any remaining bubbles should pop by themselves
since you will have put down a less viscous coating than straight out of the
can.
You can use an expensive brush if it makes you happy but it is not
necessary. Just work reasonable quickly and you should be fine.
Good Luck.

Thin w/ mineral spirits or turps and add some Penetrol. Reexamine your
brushing technique. Lightly sand w/ hardbacked sanding block between coats.
You can thin up to 20% without it running on a vertical side and it should
not leave brush marks with a good china bristle brush. I use Zar, so do a
test piece with your brand first.
When I first heard this I thought it was kind of extreme, but I was told
that the finishes have less volatiles in them now to meet environmental
regulations.
