OK, this is either a good creative idea or completely pointless! All views welcome

So, the classic place where our cars rust (especialy in the UK) are the sills underneath the doors. And if they start rusting from the inside there's not much you can do...

So the idea is this... what if there was a small fan within each of the sills which worked for an hour or so every day and dried up the sills...

More specificaly, classic computer fans use 0.22A which would mean that they can work for 170 hours or so with a full battery charge. So half an hour twice a day would be fine for the battery.

Thoughts...

It's the road salts that promote most of the damage, not just the moisture. If you really want to save the sills from internal corrosion you would need to inject a hydrophobic structural foam into the cavities. This means you would need to reroute any soft tube drains and wiring first. I really don't think accelerated cyclic wetting and drying with a fan would slow down corrosion that much and could actually aggravate it under the right conditions.

The easiest way to avoid the road salt is to buy a winter beater.

Otherwise, rinse off your car when you get home from a drive in salty conditions, and shammy the moisture off.

I'd also get a proper rust/corrosion treatment done...where they drill holes in the sills and plug them with rubber plugs.

My 1992 Mercury winter beater was done by Krown years ago...no perforations anywhere. The dripless stuff is good..its basically like Fluid Film and it creeps everywhere.

hooray for living in saltless places
