I'm reading Bob Flexner's "Flexner on Finishing" and I'm so confused, my head is spinning.
1. Varnish. He says that varnish is basically oil cooked with a resin. He says that there are 3 types of resin, alkyd, polyurethane, and phenolic. For practical purposes is there a difference between them? I'm not asking about the chemistry, but the usage. Is one better for some things than one of the others? Does is perform differently?
2. I understand that stain acts differently on hardwood compared to hardwood plywood. So how do you handle it when you are finishing a project that has both in it, like a frame and panel door? say, oak and oak plywood. Do you finish them separately or all at one time? would you always use a washcoat?
3. Is it important to store all your finishing products at a certain temperature? Should I be keeping mine in the house where the temp is very stable compared to the shop (garage) where the temp fluctuates a lot?
4. When you're working with mineral spirits, what should you do with the waste chemicals?
That's it for the moment. Thanks for any and all wisdom on the subject.
