I still like Coverstain. It'll seal just about anything too.Steve,
When I run BIN I run some ammonia/water mix thru first. If you don't the BIN will react badly with the water or pump saver My pump saver is 30W Pennzoil in the sprayer. It kind of curdles and gets cruddy and will form a solid clog in lines and filters. I know! Ammonia cleans up BIN in a flash. Apart from the smell I like the smell of BIN more than the smell of ammoniaBIN works to seal almost anything and sands easily.
I think BIN works better for sealing odors though...I'm sure if that's wrong, someone will correct me.
