The problem is, will it take the heat...... :/ and also with the brake dust will it clean up good.
I used hamerite paint, athough you wont get it in dragon green BUT you can mix it to a close match.
Maybe that is worth a thought, as it will handle the heat and clean up good.
The halfords paint you linked too is for body work, i have had some recently, it would need to be primed etc and im not sure how it will handle the calipers.
Maybe some1 else has some thoughts......
