Also from screwfix, toolstaiton, and you may as well get the gun while you are there as they are cheep enough but when you only need a small amount of the mastic and you cant be arsed to go rummaging in the shed and risk certain death (in my case ) then you can push out what you need with the other end of a hammer or something like that standing on the floor.
I don't do rain or threat there of. dry rider only with no shame.
