bed interior

[85Ram50]

I have the area behind the panels rust free and sealed with paint. I ended up getting new hardware for the fasteners. I took one of the good ones in to the fastener store and the guy told me it was 6mm dia 16mm long he didn't give me the thread count.[Edit- he did not have any metric screws or bolts that small.] I ended up getting 38 - 1/4 x 20 x 5/8 hex head bolts with washer and lock washer. I had to get the U nuts at Napa Auto Parts. See picture. If you go this route make sure you check the packages as I could only get 3 and needed a 4th so drove 20 miles because they had it. When I got there the package was identical but it had flat nuts in it not U nuts. ?? Ordered another and got them this morning. I have run sealer around the bottom and side edges of the interior panels.
The Napa part is Balkamp 6651909 which is a Dorman product packaged under the Balkamp label for Napa. I forgot the Dorman part number.

If anyone has any good experiences with DIY bedliner let me know what brand. I don;t think my compressor meant for air nailers is strong enough to do a proper spray job through a paint gun.
