Theres lots of other media, including iron particles, glass bead, plastic bead, garnet, walnut shell, alluminium oxide....huge list .....all have their own properties and uses.
Some are single use, some go round and are filtered.
Ye i was thinking about dipping but cant find anybody near me found a guy who does water media and another one near me but i was thinking of doing it myself with soda
my mate got alloy frame shot blasted he then left it his shed for a while you could little specs of rust where shot had embedded into it left a dull an rough finish no good for polishing
i think you need walnut bead or soda blastiing if you intended to polish it
I have a look into that ceramic polish 1552 any ideas who does it ye dan28 thats what i was afraid of doing it and not being able tonpolish i seen a frame after shot blasting leaves it looking white its the same with walnut and soda its the risk of knackering the frame for polishing the other thing is dipping had a bit of a look at that but i found a guy not far from me he does 3 diffrent blasting types i going to go see him
