Rusty Spindles

I have a pair of drop spindles that are fairly rusty but seem solid enough.

I was considering the mol***es treatment but had some concerns about the machined areas of the pieces getting damaged.

Local feed store has it in bulk for $2.50 a gallon so it would be cheap enough.

I had also thought about getting them bead blasted.

What might you guys recommend? I would appreciate the insight.

 

I'd blast them, mainly because I have a cabinet in the garage.

 

I may go that route since my buddy also has a cabinet in his garage. Thanks.

 

Or wire brush on a angle grinder, then use Ospho or self etching primer.

 

The rust that is there will leave the same pits no matter if they are dipped in mol***es or bead blasted. You are still going to have to take some fine emery cloth and buff up the surface the seal rides on and where the bearing races slip on (they aren't supposed to turn on the spindle so as long as they slip on and fit good that shouldn't be an issue.

 

blast them

 

The rust is "only" on the cast areas that would have been in the elements once on the truck - the spindles machined portions are nice. I just didn't know if the mol***es would have a negative affect on those machined areas. I would tape them off to blast but I'm guessing just put each in a 5 gal bucket with the mol***es water mixture and let them go for a week or two based on what I've read on the HAMB.

 

I would just wire brush them. Mol***es will eat rust free steel if no rusty steel is present. It is acid and it will eat whatever is easiest. I have ruined part to show for leaving parts in too long.

 

Thanks Andy - everyone

I was concerned about screwing them up even more with the dip so I think I'll go the brush wheel route instead.

 

Andy, regardless of the method used, you will have to paint them when you are finished, so kill 2 birds with one stone. After blasting or wire brushing/wire wheeling, hit them with some paint from Eastwood that disolves the rust and protects. Ch***is black or the Rust Encapsulator comes to mind. They have a excellent customer service dept who will help you, all the best, TR

 

I use mol***es and it wont eat the metal at all. It does takes two weeks. Won't remove paint, grease or mill marks.. They will flash rust so oil or prime ASAP.
