Wonder if there is some adjustment specific for composites. So... Wood (btw, with or without pads)? Foam? Xps would be ok Commercial available? Ifound permagrit blocks fantastic but they only make the coarser grits. Thanks

I wouldn't get the long one or the medium one though. I have them, but have used them maybe once. Get the medium one. Can't remember the length, but it's like 200mm or something. not the smallest one, but the one up.

Sometimes if you have a fixed shape a custom block can be useful. Warren Penalver Easy Composites / Carbon Mods - Technical Support Assistant

Currently just using a whole load to sand some carbon wheels, also if you are looking to buy some sanding blocks i can reccomend the perma-grit tools that easy composites sell.

Thanks Scottracing for the 3d print hint! I already have the permagrits, unfortunately they stop at a quite coarse grits. Fantastic tools though!

And often you can just sand a profile into a junk of MDF on the belt sander and it does the same job.
