steveo3002 Member Messages 7,714 Apr 15, 2020 #3 it not overly important , was just going to use whatever i have laying around
steveo3002 Member Messages 7,714 Apr 15, 2020 #4 or better off not touching the galv for better protection?
Dcal Member Messages 4,088 Location Antrim Northern Ireland Apr 15, 2020 #5 The paint will improve the protection so no issue with that. The sweep blast is to just roughen the surface not remove any galv, sanding will do the same, just not as well (or as quick)

Dcal Member Messages 4,088 Location Antrim Northern Ireland Apr 15, 2020 #8 I wouldn't use the wash under the epoxy. Just sand it well, clean it and put the 87 on. It will work fine.
