Thanks for the advice everyone.
I'm read so many options & opinions on this forum and in others that my brain hurts - so I still can't decide what to do.
Logic says sandblast, then galvanise, then paint (primer & top coats) and finally wax. But my wallet says "
" about the sandblasting stage - it's likely to be several hundred quid to do this little lot (line 2 post 1). So decision number 1 is whether to sandblast or not.
Decision number 2 is which products to use. The list is endless but Bilt Hamber and POR-15 seem to get a lot of recommendations. I contacted POR Support and they said
don't galvanise
*- go straight from sandblasting to the priming stage. So that confuses things even more.

Edit Just to add to the above: i.e. sandblast or don't sandblast. POR Support said either way will work. Using POR-15 over factory painted new parts will extend the life of the paint, but POR-15 on sandblasted parts is a
permanent solution.
Edit *The reason being (say POR) that there's no advantage over using the POR 3-step system.
