Clearcoat suggestions?

[rialtosoundboy]

Can anybody suggest a good clearcoat for the crankcases?  Now that I've got them all purdy I'd like to keep them somewhat tarnish free.  Don't know if I need some sort of heat resistant clear or if regular clearcoats will work.

I have used Plasti-kote clear hi-temp on mine. BUT it gets a bit soft the first few heat cycles. I has not yellowed yet. I have had bad results with Duplicolor paints...so I stay away from all their stuff.

They will all yellow over time, riding in rain or going to  the carwash, the motor is hot.   The coating will color. I perfer to leave my metal bare.

Its the sun's UV rays that yellow the clearcoat, if you only put three coats on you shouldnt have too much of a problem with yellowing (i don't know how thick a coat is but thats what we were told) in oz the sun can be pretty harsh, especially in tasmania where the ozone layer has dissapeared.
