Undercoating / chassis protection for EVs

[lucaspalm]

I have ordered my first electric car, and there are many things to consider. One question that came up is whether you can or should apply undercoating or chassis protection to an EV, and what products are suitable for that purpose.

If you're located in Norway, you should chech with your car dealer if they already have treated your car in Norway before delivery, or not. They should also point out which treatments are OK, and if you plan to do it yourself, a scheamtic of places to avoid or have special care of.

Tesla don't like it if you've treated your car, and by that can be one of the companies that can be a bit troublesome, especially if your treatment hit parts of the car that can be negatively affecting them, but others also have rules and regulations in this matter.

My car came treated with Mercasol, a product based on sheep fat. It's sticky, and can smell a bit in the start, but it creeps in openings and rejects water, so it's considered one of the best solutions.

Tectyl is another alternative that was very popular before, but became less popular as car owners and companies found that scratches and openings could soak in (salt) waters from the winter treated roads, and "conseal" it inside, making the water trapped and hiding long term rust attachs under the treated metal parts. And by that sometimes made things worse rather than good.

Companies that does the service, can also have som form of sound dampening of the part of the treatment, but then they have to to more extencive work, for an extra buck or two of course.

Those companies normally have access to the different car companies and car models schematics, and their policy on acceptable and non-acceptable chemicals and areas to avoid or treat well.

Mercasol = Lanolin? Nope. U mean Fluid Film?

I did'nt say Mercasol = pure Lanolin. On the little "touch up" spray can I received, and the info given, said that it was based on sheeps fat oil. Not pure sheeps fat oil = Lanolin. I did'nt check how much of the product that should have been from sheeps fat oil.

If that info is wrong, i'd blame the producer and the dealer for wrong info. They where my channel for that info!

Anyway, Lanolin is a good alternative. Maybee it smells much more than Mercasol, because I never noticed any smell at all. Or maybe I was just lucky with air and temperature, especially since I'm not parked in a garage, so venting may have been great for those days after receiving my car.

tectyl og mercasol er i det store og det hele samme opplegget. At de har tilsatt noe lanolin i touch up sprayen er vel for at det mykgjør bitumen og bidrar til feste. Fordelen i dag er at det meste er beskyttet med plast under sånn at behovet for tykk bitumen er borte. Ren behandling med lanolin eller linolje gir fordelen av at man ser hvordan tilstanden på understellet er. Tectyl/Mercasol gjør det motsatte og er veldig populært på eldre, rustne biler for å gi ett godt inntrykk av tilstanden. Det holder på vann så det ruster enda fortere bak Tectylen/Mercasol.
