My five door hatchback Laguna RTi facelift has many aluminium components in the sports engine compartment, etc. whose surface is suddenly being converted into white powder. I attribute this corrosion to the recent installation of many condensing boilers on my housing estate.
Condensing boilers have one drawback and that is their ability to create corrosive exhaust gas. This acidic exhaust gas is a by-product of the high efficiency combustion process inherent with all condensing boilers. The exhaust gas is not a pure acid but has just enough of a low pH level to corrode anything other than plastic or stainless steel. The condensing exhaust gas is slightly acidic with a pH level of three to five. Basically pure clean water has a pH level of seven which is considered neutral, anything with a pH of less than seven is considered acidic and is corrosive while anything with a pH level greater than seven is considered alkaline and is not corrosive.
Has anyone encountered a similar problem with their vehicle? Painting the components that do not get hot seems a good remedy. However, the Laguna RTi intake manifold gets hot and I am looking to apply a temperature resistant clear paint so that the engine’s visual appearance is unchanged. Can anyone recommend a temperature resistant clear paint?
