Everyone,

Two questions regarding the '58 MGA I am working on:

1. I have surface rust on the inner sill (photo) and I feel surface rust on the inside (poking through the drain holel/vents). I blew out tons of dirt but was wondering what everyone would do to try to kill the inner surface rust (there does not seem to be any thin metal based on poking with awl and screwdriver). Should I just try to spray in some rust killer or cut a small window in to get greater access, clean it up, paint inside as best I can, and weld it shut again?

2. There are lots of fixed nuts in the body. When priming and painting the car what does everyone do to keep the treads clean in these nuts? Do you screw in some old nuts to keep the threads paint free or force in a bit of grease into each so paint won't stick? Regardless I would still chase the threads after.

Thanks.

Look at Eastwood's web site/catalog. They have spray cans with long plastic wands to reach inside such areas.

Since you're going to chase the threads of the many nuts afterwards, I'd say just do that. And I suggest a re-threading tap (& die) instead of a thread cutting tap (or die). A re-threading tap cleans & straightens threads without removing metal.

If the metal is otherwise sound check out various Eastwood rust stabilizers or the old standby Waxoyl. You want to passivate and stabilize the metal so no further corrosion takes place.

Wow! it is good to see an original!
I am not too much of an Eastwood fan, but they do have a combination rust converter/encapsulator that you can get in there with an aerosol can and extension nozzle. It actually works pretty well.

Locktite makes a product called Extend. It is latex based so can be thinned slightly to be sprayed. Converts rust to magnetite, which does not rust. Can be painted after.
