Colour is the Canadian way of spelling it, but we also use the spelling of color as well. Almost depends on how you were brought up spelling it.
Just like harbor and harbour. It can be spelt both ways, just maybe not in your mind.
BTW: NAPA has Flat black primer, thats what the 240 will be!

For now anyways.
sr20meplease: so will I sand down the car with just 220 grit paper then? or proceed with 320? Even though this is going to be a ghetto job, I don't want to see all little scratches through the primer....
thanks!
