Shimano R540 rust on spokes - Page 2

If the spokes were not coated with primer prior to painting, then the paint will have pores, or very tiny holes, that will allow the metal below the paint to become exposed to moisture and begin to oxidize, or rust. The oxidation will seep back up through the pores. What you have done is removed surface rust, but you will still have some oxidation going on beneath the paint.

Ok managed to finish up the front wheel over the weekend.....

Stuff used :
- Red Primer Spray (USD3)
- Dull black Spray (USD3)
- Brillo Pads (pack of 4, USD1.5)
- 1500 grit Sandpaper (i have some in stock but they are cheap)
- Surgical Spirit (or alcohol can also be used)
- Rag (free)

- taped up the wheel (spent a good 30-40 mins doing this!)
- used brillo pads and rubbed the spokes until no trace of rust is found, the pad can even remove the original paint!
- after sanding, wiped down the spokes with a cloth and surgical spirit (or alcohol)
- immediately went on to spray on the red (oxide) primer
- wait 1 - 2 hrs to dry, then spray another coat
- next day, lightly sanded down the primer-ed spokes with 1500grit sand paper to smoothen some bumps in the paint etc (okay I not a pro...), wipe off residue
- spray dull black paint (2 coats, 2 hrs in between)

Results : must say I'm pretty happy with the results....just that had to spend an hour touching up the sides with black paint (connect points to the wheel).

Disclaimer : while its a nice DIY, if the spokes are TOO RUSTED, the spoke strength may have already been compromised....check with fellow forumers!

I attach some pics.....
