Jobs you just wish you hadn't started........!!

Flushed with the recent success at "tarting up" the rear wheel of my Cali Stone, where the hub and powder coating had long since parted company, and the coating almost fell off with relief in sheets when coaxed, leaving a horrible corrosion coating which was a bitch to clean up on a spoke wheel!! In the end, with a couple of coats of silver paint, it looks quite good.

Whilst on a high, I decided I would strip and polish the cam covers - both of which had a nasty bubble of corrosion under the coating, strangely in the same place on both covers.

FUKC - is the coating tough, unlike the hubs!!

Nitromores wouldn't touch it - nor a hot air gun - I even resorted to a blowlamp - didn't even bubble up, before I bottled out lest I blew a hole in the alloy!!

Latest ploy is an abrasive flap wheel in an electric drill - which works reasonably well on the larger sections, but not the trickier bits around the mounting flange.

Pissed off, or what?!!!

its not anodised, is it ? ..

blast cabinet the only way forward

have it blasted .....then anodised ...then painted . not a cheap way to go but best results i have had . paint has stayed on for 5 yrs of constant use .

UPDATE

Well, I persevered with the flap wheel - Solvol - green scouring pads, plus a Dremel - and now have it looking quite reasonable.
The main body of the covers look good (at a glance), but careful inspection shows I didn't really do so good around the mounting flanges,
but the overall impression is a LOT better than it did look!!

I took the opportunity to set the valve clearances whilst the cover were off - and this simple task opened another can of worms - the screws
holding the alternator cover on absolutely refused to budge - fancy using PK-headed screws there - my hammer driver can't be used because
the front wheel and mudguard are in the way - so will have to wait till I remove the front wheel. Oh, joy of joys!!
Managed to do the tappets by the rear wheel in 5th to get TDC, so all is not lost.

Took it out for a spin after tea when it had cooled down a bit - I'd forgotten the torquey grunt of the motor - all was forgiven in an instant!!
