If i use the Perma Chink ULtra 2 on white pine log siding along with the top coat. What is involved as far as maintenance in years to come when I need to restain? Will I have to sand the top coat off first?
You do not have to sand the top coat. If you have areas where the stain has faded a little you can apply a light coat of stain right over the Top Coat and then re Top Coat. It will require a light bath and then apply a fresh coat of Top Coat.
