SS power rack weatherproofing

[Smyth]

Have any of you attempted to weatherproof a SS power rack? I would have it outside in Southern California, under a patio cover but otherwise exposed.

Clear urethane. Lowe's.

Perfect. Thanks.

Do you think clear urethane would work on the uncoated insides of 3x3 power rack posts, such as Rogues? Not sure how I’d spray it in there, or how well it would disperse and cover the surfaces.
