Hi Daniel.
Mate - sorry the Euc didnt work for you..but it was worth a try.
From those pics id say youve got your technique well tuned - the right side looks great!
Knowing when to pull up is all part of a restoration - its a balance between retaining what you can at the best it could be. Striving for perfection on a PF that age is a fruitless pursuit... but what you have there is a prime example of a clean up and restore and 100% original.
Great job mate.
Once shes waxed, waxed, waxed and waxed with new balls shell be well looked after and in prime condition for a pin that old.
Sweet stuff!
