[DeTomaso] re Ceramic coat v's wrap

[JDeRyke at aol.com]

Colin, after wrapping your new headers, try coating them with a solution of 
'water-glass', also known as sodium silicate solution. In the U.S, its 
available at drug stores ('chemists shops' to you) It's used to preserve eggs and 
other materials and to repair leaking hot-water heaters. Racers use it to seal up 
porous magnesium castings. It's a thickish solution that dries to a glass-like 
compound that is insoluble in everything. Several coats might be necessary. 
Its also inflexible, so over time, it may develop cracks just like thick 
lacquer paint. Good luck- J DeRyke
