I hope I am posting this to the right group.
I have a sump guard under my car which protects it but the screws that hold it had corroded so I drilled them out and want to replace with nuts and bolts washers. As the underside of the car comes into contact with alot of wetness what kind of nut\bolt washer would be recommended ?
I went into B&Q and saw zine and galvanized nuts/bolts/washers but couldn't get anyone to speak to me to see if they were a suitable product for me.
Be glad of some advise.
