Title: Hydroblasting on a 1980 RM125T swingarm
Post by: ghostrider on May 12, 2014, 06:32:46 pm

 Just about finished this RM125T, and I have been considering the swingarm finish , it looks to have an anodised or brushed finish from new ,but my one is in very poor condition (scratchings and scuffing). Now I have 5  options"
1. rub back and prime/paint with an alloy look
2. Hydroblast (dont know if this will work)
3. spend all day and night buffing the hell out of it and hitting it with autosol every second sunday
4. buy a good condition second hand unit
5 dont be so caught up .do nothing and just get on with it

     Does anyone know how to refurbish these types of swingarms or any other trick to bring back a shine ? any help greatly appreciated as usual...

If you buff the shit out of it ..... you will loose the brushed satin look.
Hydro blast it-    then re- anodise  they look dull.
Any welds or repairs will show up after anodised

Best results so far are to buff the shit out of it .... then grain it with steel wool and ask for it to be flash dipped.

You could brush finish with scotchbrite and clear coat as an option.

I have stripped the anodising removed all the corrosion and scratching with wet and dry and re anodised on one of these arms with good results.

I just finished a KTM alloy one and found a paint at auto shop in a can that looks like factory finish and took like half a day to do. I started with stripper and wire buff.
