quick polyurethane finish questions
I'm applying polyurethane finish to the stained crib I built.
I just applied layer 1 today. despite careful efforts, bubbles survived and dried in the finish.
Getting ready for second coat.
Anyway, just some quick questions.
I'm using Minwax fast drying polyurethane. The can says to sand with 220 between coats. I've heard other people say they use a finer grit.
Also, I plan on doing 3 coats. After the last coat, if there are bubbles or other imperfections, should I do a final sanding after the last coat?
Lastly, I have to transport the crib from the shop to the house. it's a drive of several hours. If I'm on schedule, the final coat will be applied about 36 hours before I plan to move it. Will it be okay to stack the finished pieces in my SUV and drive them, or will the finish be too soft? And will it still be giving off fumes?
