The shelter tape comes in 2 thicknesses 0.6mm and 1.2mm.
I checked and the rail tape I use is 0.4mm. So even the 0.6mm is a big difference.
Will I be able too bend it around a 90° corner though? I didn't put rail saver here as it didn't really want too bend around the corner.
I can get a 5m roll of the 0.6mm for 25 euros.
