Hi i've just seen this thread i work for a powdercoaters on the northern beaches there are pro and cons to both powdercoating and two pack i've worked with both for a good few years, because of the temprature required to cure powdercoat (200c for 15 mins) any bearings, valves tyres etc need to be removed, you can't powdercoat over two pack it will just burn off and bubble up, there is a limited range of colours available in powdercoat.
As for weight and thickness there ain't much difference between the two both should be appliled to around 50-100 microns two pack would be at the higher end of this by the time you have an etch primer,surfacer and colour coat and maybe a clear coat if there both properly applied and cured i'd say they're both as tough as each other, two pack being cured at a lower temprature can be applied with the tyres on the rims (just get the beads broken and put some masking tape around the tyres) and bearings, valves in place.
At the end of the day the finished product is all dependant on the preparation, sand blasting (a general term, they very rarely use sand these days) is quite a rough finish which will need more primer and sanding to cover up but it will remove any corrosion, i've not had any dealings with soda blasting does any one know if it removes corrosion? i have a small chemical strip tank at work which i have stripped wheels in but its not ideal as again it doesn't touch the corrosion.
As a rough guide i'd charge $150-200 depending on the colour to coat a pair of rims that were stripped/blasted and had the bearings removed i'd mask the bearing and disk mounting faces.
I have no doubt you'll find people who can do it cheaper but to be honest its not what were set up to do.
Let me know if you have any questions
