Tectylation is a technique, especially for cars, to treat the metal to protect against corrosion and rust.
The verb is a bastard of the registered trademark Tectyl, which is run by the company Valvoline. Tectyl is an anti-rust agent for over 75 years.
In the 1970s, both the quality of the metal bodywork of cars and the quality of the lacquer and the way in which it was applied was so bad that after-treatment with an anti-rust agent was necessary. Valvoline was able to build a name with Tectyl at the time, making tectylation a concept.
Application of Tectyl occurs with spray guns according to the ML method (Lorin method). This method consists of drilling holes in some parts of the body, allowing the Tectyl to be internally mounted. Externe link
