As far as the nail holes go, I'd suggest that you wait until you are done varnishing, then give the varnish at least a week to fully cure. Get a couple of compatible colors of wax filler crayons. If you add two colors smeared together, it is generally less obvious than a round spot of one color. Fill the holes, then buff out with a piece of grocery bag paper. You can get the wax crayon fillers about anywhere.

If you want a smooth as a baby's butt finish, let the finish cure for a couple of weeks, get some 0000 steel wool and furniture wax and rub out the imperfections, then buff off the wax with a soft cloth.

I was in a ~$1.5Million house today (on the golf course). Still being finished up. The woodwork was awful. Doors were all splotchy, trim work showed where every nail hole was (filled with putty that wasn't high enough), then painted brown. Fireplace surround had planer marks jumping out because of the stain. I'm glad your job worked out well for you!

Thank You !!! I have learned so much - I am a perfectionist - my eye immediately goes to the flaws - It is amazing how shoddy the finish work here is in very expensive homes. That is why I have learned how to finish drywall - since we have been renovating for the last 7+ years, I have found my learned / developed skills using the right tools is far better than some of the drywall "Pros" we paid. Same goes for the trim work. Takes me longer (alot) but in the end it looks better and professional. I watched some really good guys, asked questions & bought the right tools.
Thank you again. I have one more coat to put on of the Waterlox- it is taking each coat longer to dry - the humidity isn't helping - I think it is dry & the next morning it feels tacky. It is looking so good..........
