I just bought a small unfinished table that will be an activity table for my kid. The plan is to stain it Weathered Gray (with a little brown mixed in) and then seal it. My problem is you can fit my sealing experience into a thimble and I always seem to chose the wrong one. So I'm open to recommendations - I'd like something that will potentially stand up against repeated banging from a one-year-old and ideally won't yellow the finish. Any suggestions are really appreciated!

Hi all Looking for some advice in case I'm way out there. I'm priming new cedar shingles with zissner cover stain by hand both side before I put them up. I'm noticing the primer soaks in at vastly different rates. What I'm thinking of doing is once they are up is spraying another coat of the water based 123 primer before I paint to get an even look/prime on the exposed surface. My reasoning is I don't want to put oil base in my sprayer. I did that once and the clean up is a royal pain in the ass. Is this a good idea? Edit: I'm painting them with dulux diamond exterior latex for the top coat. Thanks!
