Like the kind on the Classics Seekers nosecone?

 

i have had good success with acrylic paint, i used it on a vintage nosecone though

 

yep. acrylics will work. but if you want to match an enamel, paint it with acrylic first (primer) then paint your enamel over the acrylic.

 

Tamiya *might* work, it's got great bonding material but i only know it's effect on hard plastics.

 

I should know this... is krylon indoor/outdoor an enamel or acrylic?

 

it's a thinner based paint - closer to an enamel.
You'll need something water based.

Easy way to know - if it says "clean up with soap & water" it's water based.
