Hi Guys,

I recently finished a desk with polyurethane. I applied my third and
last cost and now when I see the desk in reflected light I see streaks
in the finish, sort of resembling dull residue. I can only see it
however when I look at it with reflected light. Is there anything I can
do to fix this short of sanding the whole thing and putting another
coat of finish? I appreciate any help/advice. thanks

Were you using a semi-gloss poly? If so, it could be due to poor mixing.
So, what to do. If thats the case, it was semi. You shouldn't use semi
for your first and second coats, only your last coat. Use gloss for
first coats and semi on the last. Mix it well. Semi is made by adding
"flatteners" to the gloss.

Strip and start again.
