DON'T LEAVE HUGE AMOUNTS OF METAL IN SULPHURIC ACID IN CONFINED SPACES SINCE ONE OF THE BI-PRODUCTS IS HYDROGEN! BOOOOOOOM!!!!!!!!!!!!! ----- Original Message ----- From: Pelle Andersson To: The Chevelle Mailing List Sent: Tuesday, February 27, 2007 9:12 PM Subject: [Chevelle-list] Phosphoric acid!
Just an idea! I assume you all know that you can remove rust with it & zinc plate it at the same time? Use a 10-15% solution to remove the rust quickly, rinse it & move it to a 2% solution to get a zinc plating preventing further rust attacks, rinse again! Use a steel brush to remove the residues & to get a nice surface. Use a hair dryer & just HOT water to make it dry quick! You can also use a 2-5% solution, leave the parts over night & use a steel brush to remove the residues & to get a nice surface. Use a hair dryer & just HOT water to make it dry quick! It might take some experimentation but it's the best way to get rid of rust without mechanical aid (sandblasting, roto brush etc.) AND it's rust preventative :-) Too strong solution will just turn the rust into some carbon like residue which is hard to get of the metal. Be careful (it's acid) but it's far from dangerous if you use common sense. I don't want to get sued ;-) Best regards Pelle ______________________________ Chevelle gearheads http://hem.bredband.net/chevellegearheads/ http://groups.msn.com/chevellegearheads/restorepics.msnw
