I would recommend something like Magmawrap over traditional glass fibre products. - I wrapped the manifold, turbo elbow, and down pipe on the Nissan and found that the glass fibre tends to go brittle once it has baked.
I don't know how much benefit you get on an N/A engine (other than keeping the bonnet temperatures down), but it did seem to improve my turbo's performance.
If money is no object, then ceramic coating is certainly the best option.
