On a CA finish; If there were sanding marks in a coat of CA, wouldn't the next coat fill those in making them basically disappear?
Not in the wood, just the coats of CA....

CA isn't any different from any other finish that doesn't melt into itself, like lacquer or shellac. Everything else will magnify whatever is on the surface under it. That includes scratches, and it doesn't matter whether they are on the wood or a previous coat of the finish. Whether we can see them or not depends on how deep they are, or if they are hidden by the wood grain. That's why it is important to always make the final sanding WITH the grain, even if we are sanding a coat of finish.

Thanks Russ. The reason I was wondering is this.... once in a while I can see scratches that I missed... so I am just wanting to keep tweaking my process so I can eliminate the boo boo's as much as possible.
I have not been sanding with the grain on the CA, but I do sand with the grain on every grit while sanding. I will now start sanding with the grain on the CA part too...
