Good evening, as stated in the title, im just curious if I can powder coat over a Zinc Rich paint.
A little back story on what my issue is.
Ive been asked to make railings with sphere rail heads as in the following link
https://www.fhbrundle.co.uk/products/0513096__Railhead_H_125_x_W_40mm_18mm_Rd_Base
Im looking to get the gates Hot Dipped Galvanised and then Powder Coated, with the rail heads being the shape they are, if hollow (im not 100% sure yet, ill need to ring the supplier first thing in the morning) if I was to hot dip them I would need to drill holes for drainage/ventilation, where I would need to weld up after and re-paint myself with the zinc rich primer, would this then be okay to Powder coat over, or should I seek an alternative method?

Thank you all in advance, sorry if the questions been asked a thousand times.
