Ive read a lot of threads about headlining and battens and panels, trying to find a good way of doing this on my longbow. I decided I wanted to start from fresh, not use old vinyl as templates or replace with more vinyl. I wanted to run battens the length and breadth at various points, rather than just short sections, not just to take ply panels but also to give me something solid to screw various things into, like curtain hooks for instance, without worrying about screwing into or through the hull. To deal with the curved sides and roof I got a sheet of flexible ply from the local yard, precut into 2.5 inch strips, they follow the curves beautifully.
I‘m using OB1 as the adhesive and also using a hot glue gun to tack them into position and hold them while the ob1 cures. Im running a heater inside while doing this to get the temp up and preheating the hull surfaces im bonding to with a hot air gun.
This has all worked well for vertical surfaces, but I’m really struggling with the overhead battens.
It took me forever to try and get one up, it just kept dropping off, I really needed three hands.
The first pic shows where it was going after it dropped off on first attempt, running horizontally along the cieling above the windows, the second is how I left it after lots of fannying around. I’ll find out tomorrow if it has actually set or not, but im not too confident, there just doesnt seem to be a good contact between the two surfaces.
The ply is 160cm long and 8mm, by 7cm wide.
So, my questions are…. Is there something obvious I am doing wrong? Am I expecting too much for it to grab and hold at all when first presented? Is bendyply actually too flexible to use like this? and most importantly, any other suggestions or ideas to make it easier?
Im wondering about velcro to hild it on while the ob1 cures, or if I ran a bit of gorilla glue along the edges a section at a time, say a foot, and held that up till the glue grabbed, then did another foot and soon. The ply is certainly flexible enough to facilitate this.
The second pic shows how I left it in the end, if I have to do this to every one its going to be a longer more drawn put process thanI even expected :)

Much easier to attach pads first, wait for your adhesive to fully cure and then screw your battens to the pads. You have discovered the challenges of getting continuous strips to stick to GRP overhead.

I had considered pads, but really want to have a framework around the boat I can screw stuff into wherever I like.
I might have to end up making an exception for anything overhead, but would really rather not. Even if its just for screwing up cable holders it would be really useful tohave those continuous runs.

You can attach the continuous batten to the pads - they only need to be 6mm thick.
