We have a cedar railing around a deck. The railing needs to be sanded prior to applying a water sealer. Two questions:
What is the best grit of sandpaper to use? I read that using too fine of a grit might make it more difficult to seal, but the article did not provide much guidance after that suggestion.
What type of sander should I use? Is a random orbital sander OK, or is there a different preferred type?
Thank you for your input!
