Well I just had a new hatch painted put on my sup, had a shop do it (because it needed to be painted). Now I have noticed rust on the body of the car where the hinges for the hatch are, I need to do something about this rust NOW so it donest get worse and start eating through the body. I know I am going to have to remove the hatch to get at this rust, my question is, what is involved in removing a hatch? And is there anything special I need to know when re-hanging the thing?.

Also is there anything I get spray/put on the rust that will prevent it from getting worse in the mean time? Wet winter is comeing :(

The hatch is pretty easy to remove. You'll have to pull down the headliner to get to the bolts for the hinges. You can just take the back headliner grommet off and the C pillar moldings and you'll be able to pull it down evough to get to them. You will also be able to get to the harness/es for the defroster/wiper and the sprayer hose. Also remove the shocks and you're all set.

You have several options....

Metalready from http://www.por15.com/ is supposed to be very good. They also have rust-preventative paint that is reputed to be great. Damned expensive tho.

Also, MetalPrep 79 from these folks http://www.buyhstna.com/store.htm

I've used Ospho from http://www.ospho.com/index.html because its cheap and it works beautifully and I can get it at Home Depot. I've even used a syringe to inject it into small cavities to neutralize rust on the inside.

Never had very good luck at all with Naval Jelly. Waste of money IMO.

Basically all derusters work alike, a mild phosphoric acid reacts with the rust to convert it to iron phosphate, an inert substance. Read how here http://www.team.net/sol/tech/deruster.html Some products add zinc or other compounds as a primer/rust inhibitor.

Once you've neutralized the active rust, you'll need to prime and paint to seal it from moisture so it doesn't come back.

I've used POR 15 on other small rust spots on my sup before, this rust is very mild but I want to catch it before it rots through. Thanks for all the input!
