Need Some Advise...

[ItsRandy]

I am expecting the last piece of wood for my bed tomorrow (it's complicated) and will need to stain and finish the wood ASAP after I receive the last board. What kind of clear have other people used? I was going to use Spar Varnish but have read it remains "soft" when it dries. I have considered urethane but I don't think there is any UV protection in it. I would like to spray on the finish because I'm not real good with a paint brush (I hate brush marks) and most clears have no instructions for spraying. I have considered using automotive clear but don't know if it is compatible with oil based wood stain. Any help would be appreciated.

If I posted this in the wrong place might a moderator please move it. Thanks!
