Greetings. Today I installed a Broan bath vent on the outside wall of
my bathroom. Because my siding is not flat, I had to cut out the
perimeter of the vent as the instructions say. I now have to trim out
the opening. What is the best way? In the second pic you see a window
that has a J- channel or whatever its called at the edges of the
siding. I thought thats what I could use. Any inputs appreciated.

The J-channel would work a lot better if the cap was sticking out
further. How hard have you mounted it? Can you yank it back out and set
it on a ring of 2x2 blocking? I have also seen purpose-built things from
the siding company for surface-mounted stuff like this, that has a
zig-zag on the back edge to rest right on the siding. Used for mounting
light fixtures and such. May be worth a look at the supply house.

(Kludges like this are one reason I'm not a fan of vinyl siding...)

There problem is not vinyl siding, but installation skill.

It is difficult to trim this out after the fact. Best would be to get a
surface mount light mount that fits the profile of the siding and mount the
dryer vent to it. Unfortunately, you already have the location cut. It
looks like a through-the-siding light mount might still fit in the hole and
you can mount the dryer vent on that.

Did you post through googlegroups? DON"T!!!!!!!!!!!!!! Lots of people who
hate spam and such block all posts from Googlegroups because they refuse to
stop spammers.

Because of how the joists runs in my bathroom, and because there is a
plumbing vent pipe in the same joist bay by the sill plate, I had no
choice but to drill the 4" hole in that spot. I could not go up,down
or side to side, this was it.
As I posted before, if I can find those mounting blocks at Lowes, HD
or some other building supply store, it loos like the best option.
