I've just come to re-fit the plastic undertrays to the front end of my Blob and the felt-like material stuck to them seems to me to be a perfect way to hold water in, thereby accelerating rust, for little apparent benefit.

Is there a good reason I need to leave it in there (eg- it stops the exhaust melting the undertray?), or can I take it out? The same goes for the stuff on the underside of the bonnet.

I have tried searching on here before posting this, but couldn't find the answer.

Thanks for any help.

 

Anyone...?

 

Like many owners I have no undertray - and I've removed the sound deadening from under the bonnet as well. No issues at all

 

+1, when I got the car the undertray wasn't there so I didn't even know it was missing. I've since removed the gearbox one and it has made spotting of my gearbox leaks easier so I've been able to fix them

 

Thanks chaps, that's got me sorted. Off they come.
