Several years ago I purchased a vapor blast cabinet to retore my own aluminum Britsh motorcycle engines. Lots of car guys have never even heard of this process. In the USA its called liquid honing or vapor blasting. In England its called vapour blasting or acqua blasting. I'd like to get some feedback from car guys to see if anyone is interested in the best aluminum restoration method in the United States. To see some good photos, go to eBay.com, search the key word 'vapor blasting' and my ad should pop up. I'll be interested to hear if you car guys like the results. thanks, Jeff Gibson 503-876-8740
