Merckx owners thread

Anyone got any recommendations for a spray/grease to apply to my bike to protect the paintjob of my bike and stop it rusting?

Also made my bike much more ready for the streets of Berlin.

• Switched up the tyres to 28 conti 4seasons
  
• The shifters were knackered, so took them to a local bike shop and had dura-ace 8 speed shifters fitted
  
• The bar tape was manky, so switched to some black lizardskins bar tape
  
• Switched pedals to flat/spd XT pedals to allow me to cycle clipped-in or in normal shoes in the city.
