I want to seal the signs I made as an extra measure. I have Aqua Mix UltraSeal and Helmsman indoor/outdoor urethane. Would either of these be ok? Does anyone have a preference? Thanks
Is that Helmsman marine spar varnish?? I"d be worried about yellowing
No it is just regular indoor/outdoor spar uretahne. Can't seem to find marine anything. Is there anything anyone might recommend?????
