Forks have polished up and seatpost add in wanted section. The bike came with alloy bars and seatpost. The rest is how it came from the shop. It was built by the shop with these parts so all the bits are staying but getting some TLC.

I had to use scotchbrite on my painted ripper.  The paint shifted ok with nitromors, but the etch primer underneath was hard to remove.

Mind you I was going for the shiny look.

Didn't use any glass paper though!

I was thinking more you would need to sort out any damage first like deep scratches as the acid will only etch the surface. I bought some really evil paint stripper from HMG coatings that made the paint on the specialized frame almost pop off.

No don't do it, you won't be leaving the acid on long enough to etch the surface and if you start flatting off the scraches it'll end up patchy, I'd just leave the scratches and clean it.

I see, once you start messing with it you loose the original ball burnished finish, something I did on mine the first time it got scuffed unfortunately.

This is it as it is now, bit too shiny compaire with how it was new.  I have re-fitted the DX pedals since the picture was taken and the whitewalls have calmed down a bit !
