I need to squeeze some silicone sealant into a tight spot along the joint between the shower tray upstand and the acrylic wall covering. There will be a gap of about 9mm but I will not be able to direct the flow of sealant upwards as is needed because of the shower tray. A small right angled tube attached to the tip of the sealant nozzle would do the trick. Ideally it would be about 10mm long on each arm of the right angle and an internal diameter of about 5mm although size isn=92t critical.
Any suggestions of what I could use for this would be greatly welcomed.
