I happen to be looking under the car yesterday while getting ready to cut inside to remove the snapped transmission cross member bolt and I noticed one of those rubber assess panels are missing showing the primed unpainted inside of the car.. a little rust has started but what can I use to cover it back up with?

Seeing how it has one on the drivers side the only way I can see how it was missing was when someone pulled it out thinking it was something else? I was thinking maybe using some thick window sealant or some RTV would do the trick? I have some precut cutting boards I can cut down to size and cover it.. it's thick enough for it.

spray undercoating is what I would use.

 

O.

Is that something that's going to be hard to find?

Autozone has the above 3M rubberized version that will be less likely to drip into your eyes.

I tried looking for that stuff in autozone this morning I did not see it at all.. One also thing I did not notice is it can be used as sound deadening.. anyone try that before? I should check to see what the spray looks like I would like to see if it's worth putting inside on the floor under the carpet.
