So I'm back and forth on having our new model 3 protected from all the salt and grim that accumulates over the winter months here in southern Ontario. I haven't come across much info on this, whether it's a good idea or not. I'm guessing this is due to the model 3 only being around for the last 5 years, so maybe issues will start showing up soon. I've come across posts on the warranty information, and that the warranty is void if you apply an undercoat or rust prevention spray. Unless Tesla has done something special to the components of the car I can't imagine the car will withstand multiple winters with no corrosion or rust. I've been chatting with a guy from a company called HoneySeal in Oakville, Undercoating | HoneySeal who has mentioned they have an EV friendly product. If I get this done, this is the product I'm going with. I'm curious if anyone has undercoated their car, and if so, what product have you used and what was the process like.
