Seams questions

[alittlebohemian2012]

Hi all,
Next question of the morning. So, when i'm ready to pull the seams off....If needed can you buy replacement rubber & the rack? seam thingy they go into? Does this question even make any sense?
I have attached a pic so you can maybe see what I mean. So heres the short story. After driving for about 4 hours we stopped for gas. As usual I did a walk around the camper looking for anything suspicious. Well didn't have to look far. This is the front left corner. The seam was exposed & pulling off. I could see the extensive rot inside but since we were enroute to our camping destination, naturally I did a quick fix with some L clamps & deck screws. Just to get the old girl home in one piece. Oh, and yes, I did say a prayer constantly on the return trip. So, now I will have to address this problem. But for the moment I am working on the floor & frame in the rear. As I go along I will fix the seam / track.
Any suggestions? Comments, words of encouragement? Thanks guys. Hope to see you all out on the road someday (instead of in the garage).

That looks like the aluminum channel trim molding with the vinyl insert that slides up the channel to cover the screws, is that correct? That's a more modern way of trimming the seams than the older trailers that most folks here have. My '76 didn't even have it, just exposed-screw J-rail. But you can get the vinyl inserts lots of places, like here, and they probably sell the aluminum part too, I would think: www.shoprvparts.com/product.do?no=14194F
Some aluminum moldings are here: www.yellowdogextrusion.com/extmold05.htm
Of course, you have to get the insert that fits the particular extrusion you buy. If your aluminum is still good, you can just buy the insert vinyl. But it's a piece of cake, mechanically.
