I washed the car about 3 weeks ago, then when doing some other mucking about yesterday raised the back end in the air. This morning found a drying puddle of rusty water had come out of one of the front chassis tubes (car has been rolled forward several inches before the photo was taken). That water gets into the tubes I never doubted because of the many visible openings at tube junctures. But I was unpleasantly surprised to see it is retained there, as the car had been driven several times since being washed. I've never driven in the rain, and don't intend to do so, but those of you who do may want to take note. So add internal chassis corrosion as another thing to deal with. Probably will add a few strategically placed weep holes and waxoyl the bejeezus out of the horizontal tubes. The things the factory didn't get right and that owners need to attend to will fill a book one day.... ![[Linked Image]](https://www.tm-img.com/images/2020/06/12/IMG_0290.jpg)

I've run an endoscope inside quite a few of the chassis tubes on my chassis and the previous chassis too! The first thing I did after the first time was get some Dynax S50 in aerosol form and sprayed as much of the internals as I possibly could. There are lots of mouse-holes in the tubes that let the lance supplied with the aerosols inside the tubes. Give it another ten years and I'll be able to tell you if it was worth the effort or if the corrosion has found its way out through the tube walls, till then I am reasonably hopeful that it does quite a lot of good. One of the things I found inside the tubes was the number of holes that are drilled in the tubes but the insides are not de-burred leaving lots of thin sharp swarf attached to the tubes and lying inside them for the corrosion to get started on.

Waxoyl... not a term I've used since the 70s! Used it only last week, still good stuff I keep a jar on the bench with a brush in the lid, if a nut or bolt is taken off for any reason - it gets a dab on re-assembly

I didn't think you kept a chassis long enough to corrode Calum
