Yes I have a caterpillar twenty Inherited from my grandfather.I was informed it’s highway yellow I should be looking for?Im trying to restore it as I grew up with it.Any one know where I can find it and how much does it run it?or is that even the right type of yellow.Thank you-Joey 

old cat yellow is the colour available today. nearly all paint brands that have a equipment enamel range will have it. and its quite close to the original highway yellow that basically is what the school buses in America are painted as it was originally developed for the federal dept of transport. it was also used on road maintanence and construction vehicles.

any paint shop will have it and any farm equipment joint will be able to get as most stock bareco products. the cat dealers also have it available. the thing about yellow colours is they fade easily so no it wont look the same.

in reality colour doesnt matter you paint it what you like.

It appears to have the best kind of paint already on it, Its called original!!
