I've decided to try to step up to spraying finishes. I've acquired a Harbor Freight 43430 gravity fed hvlp gun. My first step will be spraying SealCoat. I understand that SealCoat is about a 2 lb. cut as it comes in the can. Is this a good consistancy for spraying or should it be thinned? How do you determine the proper consistancy in general? Is there a magic formula depending on what you're spraying and which gun you use or do you just try it and see if you like it?
