FV 432 Preventable Rust issue

[robin craig]

The newest 432s coming out of Withams are Mk2/1 with Bowman updates.

 

The flat surface that once held the swim screen on it many years ago has tapped holes in it to receive that screen.

 

Some bright spark did not think that these holes should be sealed. As a result the void created by the mounting surface fills with water and corrodes this area from the inside out.

 

In addition at the front there are two slotted openings into the same void. We are cleaning ours up, tapping the holes and going to install bolts with washers into those openings and then inject rust preventing oil inside. At least thats the plan unless anyone comes up with a better idea!

 

As usual, poor quality phone pictures but you get the idea.

spray inside with waxoil or the Canadian/American version of it that will stop/slow it down more importantly stop it liiking unsightly.

MOD curent stuff is called Vactan. Water based and excellent covering quality.

clean up top surface fill void with oil then cap with green silicon

We tapped the holes and bought some bolts and washers and broke open the "goo" and filled all the upper surface holes and gave it a lick of paint.

 

Now that is done we will "dry" / dewater the inside of the void and then treat with rust preventer, likely we will tap and plug the drain holes but still not sure of that or how we will do that. I'm thinking it should be vented but an inverted U shape so it can breathe and not drip down the side.

 

Here is a photo of the result so far.
