Subject: [PSUBS-MAILIST] Paint on Galv.

Hi All,

I just had a talk with a company Altex about having my buoyancy tanks grit blasted, then zinc metal sprayed then painted.

They said don?t Zinc metal spray.  Aluminium metal spray is OK.  What they said is that the water will penetrate the paint and activate the zinc and paint will come off.

I guess the same applies for galvanizing then painting.  Does anyone have any comment on this.  Also with Aluminium bolted to stainless steel they said don?t use stainless bolts use monel.

If it is true what they say it is another caution for P-subbers falling into traps.  Hugh

 

Problem with getting older is that I?ve forgotten whether I have forgotten or never knew!
