Thread: Boat Trailer Maintenance Time

I'm a big fan of bearing buddies. I only fill them till I see the spring move, a little often is the secret.

As for bearing buddies. Fantastic. My old boat which I sold to another member .I out new bearings amd bearing buddies as soon as I bought it.in the ten years of my ownership I never failed a warrant and the bearings were mint.never had any issues
My mate whi worked for a bearing company said pump them up all good when the overflow hole weeps on that model of bearing all good stop. If the grease has come out the back of the seal.then it's failed .

wash trailer well and coat it with this stuff.
https://prolan.co.nz/product/enduro-heavy-grade/ after coating it tacks up (doesn't dry just goes all tacky)
after treating don't waterblast just hose salt off with lower pressure

keep it all in perfect nick (can look quite rough as all the road dust sticks to its but keeps it all mint and rust free

recoat every 12months. we use an air compressor with a paint sprayer but a manual squeezy spray bottle or a paint brush works.

I thought there was cases where lanolin and some dunbier trailers reacted and actually made the trailer corrode badly.read.it somewhere whole ago.

Yes i have seen this first hand. Mates trailer that he coated in lanolin. I told him not to do it, but, then the galv was buggered within 12 months and had to be re dipped.

It sort of went crappy and flaky within a few months. I wouldn't use it on any galvanised items.

I doubt the galv reacted with the lanolin- but you could very well have sealed something in under the lanolin that caused the reaction (zinc is one of the most reactive metals hence it's use for cathodic coating and protection of less reactive metals).
