Post Subject: Hot metal spraying

Any comments or opinions about metal spraying as an alternative to conventional blacking (other than cost!)

Post Subject: Hot metal spraying

The only thing I have known hot meal spraying being used for was building up worn shafts and then the shaft had to be heated up to a high temperature to help the metal spray flow and adhere. Nit sure how one would heat a boat's hull to such a temperature. Come to that I am not sure how you would get it clean enough. If you intended to sand/grit/water/soda blast the it would be a good candidate for a two pack coating. Tony Brooks

Thanks for that. Yes I will grit blast back to bare metal first then have to decide whether to hot metal spray (zinc) or two pack as you say. Really I am trying to find out if anyone out there has any longer term experience with the process on narrowboats.
