Ceramic paint for manifolds

We measured the wall thickness on my failed manifold - .030 to .045 - way too thin. No ceramic coat will fix this.

 

AFAIK the blown manifold problem generally occurs on the middle two cylinders/pipes on each bank. The pipes are just a tad too thin and they blow through eventually. Since all four pipes are encased inside a heat shield there is nothing you can spray on them that will help AFAIK.

If yours start to blow you will first notice a fine white dust around the engine bay - the wadding being blown out from the heat shield.

The only solution seems to be to replace. FWIW QV nr London in the UK get 355 manifolds rebuilt with slightly heavier guage pipes & sell them out at less than half of the price of a new one.

I.
