I would rethink the herculiner on the inside. Its a pain to clean, the alum you have now you can spray down with cleaner and wipe perfectly clean. The Hurculiner traps dirt and crap and is a pain. I also personally don't like it for the outside but your call. Reasons are the same for the inside. If you do do it, make sure you do fanatical prep work. I had a custom steel bumper made for my truck and used that stuff. It lasted 6 months and started peeling. It got REAL old redoing it all the time. If you have the coin, powdercoating would def be my first choice and look awesome. Maybe you could trade your skills with the coater...
I'm not planning on bedlining the exterior at all - only the interior. As long as the bag seals properly, I'm not sure how it will get dirty inside unless I put dirty boots or the like in the bag.
I used to do custom paint, so I know about proper prep. My rule of thumb has always been "if it's shiny, it's not sticking". I will degrease the inside first, then sand with 80 grit until there is absolutely no shine to be seen for the liner to have a "tooth" for a good, mechanical bond. Then I will degrease once again. A lot of times people will actually grind impurities into the base by sanding before degreasing. And even degreasing has to be done a certian way - i.e. - if you just smear degreaser around, all it's doing is moving the impurity to another place to dry. I always use a rag with degreaser, followed by a clean rag to mop up. Once the clean rag is saturated, get another one.
So yeah, I think the bedliner will be fine for what I want it to do. As a plus, I think it will keep loose items from sliding around so much. I'm trying to stay away from powdercoat simply because I'm tying to keep it 100% D.I.Y. plus I do like the look of the unfinished aluminum.
