Don't worry about the "nibs" until you are finished. Then rub it all
down with a paper sack or printer paper.



I sanded very lightly with 600 grit following the 2nd coat (and several
days), and applied the 3rd coat. I noticed a blemish (1" by 1/4")
created either by the blue nitrile gloves or by the sand paper. It is
still visible following the 4th coat which I applied without sanding first.

My thinking is that I should give it 24 hours or more to set, and then
go back to the blemish with the 600 grit (I have up to 2000 grit). Is
this the right strategy, or is this likely to just make the blemish bigger?

Thanks,
Bill


No..
600 is for wet sanding a final finish.

2000 is way overkill.. used for the glossiest of finishes (especially
when I was building model airplanes)... and great for tool edging.

If you have a blemish what kind?

if it is a fish eye or rough patch, sand with 220 or 320 to knock it
down and put a new layer on after cleaning. If it is deep, you will need
to use 180 to 220 to take it down a layer or 2.. then reapply your finish...

BTW you can reduce fish eyes with a fish eye killer. I got mine from an
auto paint shop years ago. Now we have no auto paint supply shops where
I live now. You can probably get some at a good paint store.

I think mine was Raja fish eye killer. I can't read the label anymore.
1 drop per pint - quart (already thinned) that's all thats required..
it'll last you a long time.
