Best anodizing guide?

[Doddy]

It's becoming difficult to find - presumably because by July it will be illegal (punishable by prison/fines) to sell sulfuric acid above 15% conc. to any non-EPP license holder (and by November, illegal to own it without a license). Battery Acid is normally around the 30% conc. - around the strength touted as required for anodising. Hydrochloric acid is illegal above 10% conc. which buggers up anyone looking for alternatives to ferric chloride for PCB etching at home. Today, I can find hydrochloric acid advertised for sale on eBay at 35% conc. - I bet if you tried to buy it it would quickly be removed from sale.

The EPP license is within reach of the public, but at a cost of 40 quid every 3 years - for each and every substance identified on the license, it makes casual dabbling with plating and/or anodising something that needs careful planning. It makes supplying the chemicals a complete pain in the arse.

Acetone looks to be under the glare of government - expect that to become illegal next.

I blame Europe. And the idiots running around harming people.

EDIT: My bad - Hydrochloric acid is not a regulated chemical, but is a notifiable one - so any suspicious activity surrounding the sale is reportable to the police. As are a whole bunch of traditional fertilisers (okay, so my interests - electronics, some limited form of CNC toys, and Sunday down the allotments - all going to get me into trouble!)
