By fuck, that's it done. Tomorrow, some painting action.
At nowhere at all as it turned out - rained all afternoon and the same tomorrow by the look of it. I shall have to make up some phosphoric acid based primer/rustkiller first, if I can find a recipe.
Shame, I had a consignment went off to Ireland on Thursday, I cold have put some phosphoric acid in and asked them to send it on How urgent is it?
The acid isn't a problem - I have a litre of conc. but just want to find out what Trustan23, Kurust, etc used in their mixes. My small supply of T23 is coming to an end and there certainly isn't enough to do a trailer chassis. I'll make up some simple water dilutions of 10, 20 and 30% to see how weak I can get away with, but I suspect there was more than just phosphoric acid in the aforementioned products.
<dons old COSHH overall> The composition will be in their data sheets No phosphoric acid in Kurust www.icipaints.co.uk/files/pdf/safetysheets/SDSHM140.pdf http://en.wikipedia.org/wiki/Tannic_acid#Uses This might help, although a bit vague at 10-30% http://www.jenolite.com/Jenolite MSDS.htm
Much obliged for the brown coat, guv. Tannic acid is a surprise, but istr Kurust changed about ten years ago, and I'm fairly sure it was phosphoric in the old formulation. Whatever, the info on tannic is welcome. Aha, it's helpful though. I'm on the right track.
