Did of course try and sort chemical dip. It's not readily available in Ireland though. I say not readily available - there are big chemical tanks here being used to strip even bigger stuff than my chassis every day of the week, as part of the hot dip galvanising process. I made more than a few phone calls trying to convince galvanisers to dip my chassis [without galvanising] but all said no.
Prob is you have to have another tank or specialist area to wash down the item after dipping to neutralise the chemical strippers. I asked why no one in the galvanising industry here has invested in the extra area so that they could capitalise on diversifying into the stripping market. Simple answer was it might cost €150k to make provision for that work, and you'd be a long time seeing that investment back.
I would have been blasting you heard could warp steel Bob, as Andy was saying in the video, too much heat and/or pressure can stretch the metal if blasting isn't done correctly.
