Well i bought some crossover wrap and after reading a bit about it, i was wondering if its a good idea or not.

I've seen that people have just wrapped the crossover saying not to use silicon spray on it because it will trap in water and rust the crossover.

Others have said that you should use silicon on it so fluid doesn't drip on the wrap and ignite.

Anyone know if its a good idea to do this at all, or what the best way is? also should i remove the crossover's heat shield and wrap, or just go straight over it?
