Work Required

(This is in some sort of vague order)

  • Strip existing paint and rust
  • Rustproofing
  • Replace all seals and serviceable components
    • £165 + vat + delivery for a complete set of seals, O-rings, and grease. Need to provide measurements to Clark.
  • Welding/fabricating replacement parts where required, i.e. wheelarches, reflector arms

Paint Stripping

There is some Nitromore in the engine compartment and some rubber gloves in Velyks's memberbox. Directions for use:

  1. Pour amount into metal bucket
  2. Dab on a thick layer over painted surface so it's all covered
  3. Leave for 40 mins
  4. Use scrapers to scrape paint off
  5. Clean brush and bucket when you're done

Try and work from the back towards the front.

ALWAYS WEAR THE SAFETY GLOVES AND CLEAN OFF ANY GUNK YOU GET ON YOUR SKIN. THIS SHIT IS NASTY

Replacement Screws

We might as well replace some of the knackered screws. Especially as we damaged some removing them.
