good alternative to wd40??

I know we've got some camping guys on here. Ive got an 85 Scamper popup i'm getting ready for a trip this weekend. Surprisingly everything still works on the thing but every time I pull it out things are a little tough to get moving. I've been using PB blaster to loosen up the bolts and hinges here and there, but I'd like something similar that I can spray everything down especially when I close up and store it again, especially since i'm taking it to the coast this time.

I have Shin Etzu i'm going to use on the slider rails and the crank pulley, what's the best spray stuff in a can. I know better than to use WD40, although might not be a bad idea to keep the salt water away.

Also the AC fan takes a little jimmying to get moving. Any advice other than spray lube on the nose of the motor? That got it to start if I set it to High, but not on low, and I couldn't get the cover off to get a closer look since the cover screws were seized.

I like Silicone Spray. WD40 is not a lubricant, and collects dirt/grime.

Boeshield T9 is also very good stuff. I've been using it for 15 years in situations where I needed a light waterproof lube that can also provide some rust protection, and it has always worked as-advertised.

Fluid Film is awesome... doesn't dry out like others seem to do. Several of the local hardware stores carry it, but you can always get it at any John Deere dealer. JD uses it a lot.

Either one available at Home Depot / Lowes? Neither one is available on Amazon for prime one day.

Edit, lowes has Fluid Film listed on their website but doesn't say whether its in store or not. I gotta run by tonight anyway so i'll check.

Any more backup suggestions? Sammmmmmmmm, any particular brand? Or is it the Liquid Wrench stuff?

^No particular brand..I think the last can I bought was Liquid Wrench brand from HD or Lowe's.

I like the DuPont spray lubes. I use multipurpose for certain things and the dry Teflon of others.
