Damaged the under side of my car leaving a festival last night and didn't see the ditch until after I beached it, far as I can see I've damaged the feul cooler and scraped some under seal off. There's no leaks or anything just bent quite badly, drove home okay but is it safe to drive still?

wash off buy a tin of underseal and respray it ....

if the fuel cooler isnt leaking then it should be ok i would imagine
