I'm about to spray a lot of trim with my newish Mini Mite 3 bottom cup gun. I plan on priming with Coverstain thinned about 15% which has worked well for me on some doors. I was planning on going with BM Satin Impervo WB after hearing so much good about it. I've used this in the oil based product and love it but I think it will be much quicker spraying the WB. It has been suggested that SW ProClassic or their Pro Industrial Water based alkyd urethane would work as well, but I haven't heard much about either. I know I will need to thin it considerably, but I was hoping that someone had used one or more and knew about how much to thin it to start with.

Also, if I thin it a lot, say, 20%, will 2 coats cover well enough or should I plan on spraying multiple coats?

I plan on going with a white of some kind.

Thanks, Dan
