Still thinking about the coating/protection of the intakes and valve covers.
On roadfly someone mentioned this product.
Apparently one can also use this to protect/coat motherboards or electrical connections.
I have a problem in summer that the audio freezes, most probably because of too much moisture on the circuit boards in the audio system, in winter it works fine. Summer/raining season we have over 90 % humidity.
Anyone tried this product?

Ive used silicones when doing computer motherboards before. It works for a little. Then what tends to happen is the heat created tends to lift the product, water gets in somehow (since PCBs are somewhat porous) and now you trapped moisture instead.Quote:

If your trying to protect a PCB what you want is a conformal coating. The coating comes in a variety of formulations but it is applied to the PCB and it seals it against moisture ingress. We use this when we have a product we're designing that may get moisture in it. For prototypes we buy the coating in a spray can at a local electronics store. A Google search will turn up a ton of resources for conformal coatings. Good luck.

Thanks, that is the magic word, Conformal Coatings.
Did not know that in English.

So what would be the right stuff then for aluminium engine parts which do not get that hot, such as intakes and valve covers?
I have brushed off the Cosmoline protective BMW paint with a household steel sponge (for cleaing frying pans etc) and it looks quite good NOW. But somehow I want to protect that now with a good coating (no color) wich is also resistant against some heat, fuel, oils, dirt
