I am working on my S2000 kit which I sprayed with several coats of Tamiya Chrome Yellow. I plan on using Tamiya`s clear coat as well, but was told you have to be very careful using it over top of Tamiya`s other colors because of the possibility of cracking. My question is how long should I wait before applying the clear coat? Should I use it within half an hour of the last coat of yellow? Should I leave the body cure for a week or two before putting the clear coat on? Anyone have experience with this?
