Stripped tank corrosion

    Hey guys.  Looking for some ideas.  I stripped my tank about a month ago.  I put about four coats of clearcoat on it, but it's already starting to rust up quite a bit.  All surface corrosion at this point, so nothing eating through the metal.

    I'm going to sand it back again this weekend.  Any other products I can use to help delay the rusting process?  Would an etch primer help?

     Ideally I'd like to do it myself and not bring it to a shop.

    Appreciate any help!

    Did you use Deoxidine on the bare metal before the clear ?

    Nope! Can I pick that up at Repco or something similar?

    You should be able get an equivalent from an auto shop.
    It's based on phosphoric acid, and you mix with 2 or 3 parts water.

    Cool. So that to clean, then clearcoat on top, should do the job?

    Prepsol the same I guess?

    Then something like an etch primer on top of that, followed by clearcoat?

    If your after the bare metal look you can't etch prime.

    So I picked up some Septone Rust Cleaner (same as Deoxidine), and Wax/Degreaser on Saturday from Supercheap Auto.  This is what I used:  http://www.septone.com.au/detail.asp?item_cat=11&item_number=359&page_num=1

    Sanded, cleaned, and applied the Septone to my air cleaner cover to start. Then four coats of clearcoat. All seems good so far. Will need to wait a bit to see if it still corrodes.

    If this works I'll do the same to the tank.

    Only problem is I think I inhaled too much clearcoat haha. Used a spray can. Man that stuff is toxic as hell. I've been coughing up crap with a tingly throat for over two days now. Should have worn a mask!

    Thanks for the pointers!
