lumpy finish

[Petergrout]

Hi All I think I have paid the price by applying Dingotone in the cold weather plus the humidity wouldn't have helped. It has now been close to a month and the finish is still a bit sticky and lumpy. My question is if I rub it back to smooth can I use a clear spray laquer or will this have nasty reactions with the dingotone?
