mike changed my mind about powder coating the tank,going to be zinc'ed then wet painted 2k,not as durable as powdercoating but theres not many options.
the tank should be back this week from being repaired,i never thought about using another tank as i had heard people have and problems with them.
i would deffo give bettablast a go mate i wont take mine anywhere else now,ask for billy tell him i recommended him,if you need to see his work your more than welcome to come and have a look.
