Is it a good idea to plug everything up? Air circulation is key.
I lost one of the rear plugs next to the receiver also. I don't know if I caught a rock or what looked back there and it was gone.I have'nt seen an "expensive" kind so I could'nt tell ya if these are the "cheaper" kind. I will say I have already lost one of the rear plugs next to the reciever.
I found out about Fluid Film thru this site and local Auto Parts store carried it, its a waxy film that sealed the inner tubes. Yes it gave it a cleaner "finished look" its also one less place for dirt or water to hang out and possibly rust.
