It has been highly recommended by some people that I have talked to with few people having anything bad to say. | | | | | Joined: Jul 2005 Posts: 169 Wrench Fetcher | | Wrench Fetcher Joined: Jul 2005 Posts: 169 | Adhesion problems adhesion problems adhesion problems!!!!!
PPG, Dupont and few other WILL NOT warrenty their paint when soda blasting has been involved.
Also soda is salt, salt plus metal equalls rust...Eric | | | | | Joined: Feb 2002 Posts: 12,029 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Feb 2002 Posts: 12,029 | Eric - many things are "salts", but sodium bicarbonate is not sodium chloride - in fact the simplier form, sodium carbonate [soda ash] is used as a rust inhibiter, boiler descaler, and water softener tex - see this post in the tool section - if you decide to have a commercial soda blasting service do it for you, make sure they do it in a way that avoids oil from the compressor contaminating the media and that it's well rinsed with water afterwards Bill | | | | | Joined: Dec 2001 Posts: 14,522 Moderator: Welcome Centre, Southern Bolters, Legion Hall | | Moderator: Welcome Centre, Southern Bolters, Legion Hall Joined: Dec 2001 Posts: 14,522 | Texas51: I personally visited a shop a few months ago that does soda and sand blasting. The fellow, named John, gave me quite a tour of his facility and here is MY prespective. If you are taking of any rust, (other than LIGHT surface rust) sand blasting would be best. If you are wanting to get off only the paint and light oxidation then soda will get it clean and smoooth. I say different stages of each. This guy is good and does the work for a local Mopar restoration shop that turns out some very nice automobiles. I do not know what "other" processes or chemicals or steps they use to get the end results but as for "cleaning the metal" I would go as mentioned above. Just my nickels worth. | | | | | Joined: Jul 2005 Posts: 169 Wrench Fetcher | | Wrench Fetcher Joined: Jul 2005 Posts: 169 | Things might have changed in last few years concerning the make up of the soda. But it still doesnt change the FACT that three major paint companies do not warrenty their product line when soda blasting has been involved.
That should be enough to say "hey maybe this isnt a good idea" | | | | | Joined: Jun 2005 Posts: 191 Shop Shark | | Shop Shark Joined: Jun 2005 Posts: 191 | sevt_chevelle, I agree with you 100%. There's another thread on the same topic here: ToolChest Thread I've sent a message to BarryK asking him to come lend his expertise in this area and clarify what might be some misconceptions. | | |
