Hey, Tom. On a few other threads and photos on this forum it looks like some folks install the bulkhead then apply the bedliner, basically sealing it in. Others have said they shot the bulkhead seperately and installed it after the whole tub was shot. There was one thread here in particular that stated that the buildup from the bed liner was close enough to the original bulkhead gasket that it fit great. I am not sure how I will do it, I was thinking about masking off the area where the bulkhead mounts during the first one or two liner coats, then remove it for the last spray(s). For me it will depend on how thick the liner I chose will go on per pass. I am going to try the Pro-Tex liner by SEM. It seems to have good reviews on the web, I'll cross my fingers and hope it is good. I plan to shoot it from the tailgate to the firewall...there is a really nice thread here with some folks that have done this. One of them used a tinted liner (color matching?) and it looked really nice in the photos. If you search for it here I believe he did it in red to match the body. I am plannnning to use a tinted liner, too, and contacted the manufacturer about it. Of course, they said it will match if I mix the pigment properly. I did ask about spraying paint over top of the liner if I didn't get a perfect match. They said this was possible if I waited until the liner was fully cured, sand it with course paper and spray my paint over it. They did go on to say that top coating with paint will make scuffs more noticable since you will be rubbing directly on paint when you throw things in the bed. Anyway, hope this helps. I will hopefully be doing mine over the next month or so and I will be glad to post my results.
Sincerely,
