That's prolly for a perfect, ultra-clean sandblasting job.
It's expensive unless you can catch them already mobilized on a jobsite somewhere and make a deal.
Put 'em up on your "guide-ons" where they are out of the water. They will live longer.
If you're going to stay with the little tires and wheels, get a spare.
Also make sure you clean and re-pack all your bearings with water resistant, boat trailer bearing grease.
I try to keep my bearings out of the water when I launch my boat.
Hot bearings will suck water into the hubs if you submerge them.
Yeah and Im gonna get one of those wire brushes and sand the trailer that way. It wont be professional, but it'll be the best i can do.
Yeah i got submersible trailer lights and thats where i'll put them.
I will buy some grease next time im in Walmart.
Thanks for the responces.
