I went off to the wood shop to try another finish (my nemesis) and decided that spray on lacquer would possibly be nice. So after getting a couple of bits of nice exotic woods and sanding stuff I picked up a tin and headed off home.
I finished sanding my latest bit of wood, shook the can vigorously for two minutes and then gave it a good spraying.... it was thick, goopy, blotchy and generally looked like crap. I examined the tin more closely and realized I picked up the water based acrylic shit next to the lacquer...
Waited until it was dry and then sanded it all off again.
