Have red pine 1/2 log siding with sikkens one coat process on it….now sikkens says i can not go over it and need to strip off the old to apply with their new log and siding product…what type of company would sell you a high end product that you can not go over the top of to freshen up its worn down finish…what can i do? or do i bite the bullet and pay someone to media blast the sikkens poor quality product from the siding
