Title: Soda blasting - worth a go Post by: libbyvic on 29 April, 2010, 07:19:06 AM I have bought a soda blaster for £159 from Millar soda blasting on ebay item 260593276924 and it is a great bit of kit. Never tried it before but was faced with a very dirty and oversprayed engine bay on the S1. Very easy to setup and get going.
Castings, internal pressings came up clean in seconds.

Got before/after photos?

Son Jude used it to blast the carbs on Freyja's Alfa Spider and they look excellent. The essential is the use of soda bicarb (soluble) rather than sand!

Does anyone have a cure for the pitting. ???
Title: Re: Soda blasting - worth a go Post by: roddy on 10 May, 2010, 10:29:28 PM If you are going to have the wheels powder-coated (which I would recommend as it seals any porosity), then I believe you can fill any pitting with "chemical metal" filler. It will not dissolve with the heat from the oven, whereas ordinary body filler will. I have no personal experience, and would imagine that you will have to be very careful dressing down any surplus filler as the mag-alloy is very soft.

A lot of useful tips and caveats. I am put off by the mess as I have only an enclosed workshop in which to do the work and it seems outdoors is best. Maybe I should buy a farm .................... but then I wouldn't have any time for the cars !! www.mig-welding.co.uk Good luck, Andy PS any news on delivery of the car ? Title: Re: Soda blasting - worth a go Post by: Parisien on 04 January, 2012, 09:50:05 AM Cheers for that Andy, no doubt am following in the footsteps of previous restorers queries both on this forum and others.
Will see whats revealed on initial strip down. P |
