Rustproofing - Bad Job?

Good evening everyone,

I need some help to objectively judge a rather pricey rustproofing job done on my Defender 300 TDI. The garage used FluidFilm products for the inside of doors/chassis and the black fluid film stuff for the underbody. I had this done just last week, and I am not very happy with it. While there are some obvious problems, I'd appreciate your opinion on the following points:

1. The tank, axles, differential were not covered at all. I believe they should have been. Am I right?

2. The inside of the chassis is only partially covered in some areas. Surely this is not correct? See here:

3. The rear door is rather artistically covered in FluidFilm under the cover. See Image below.

I'd love to get some second opinions on this and appreciate your support.

1. Yes
2. Yes
3. ****e..

Chassis pics look like you are just spraying on a rusted chassis, not the worst thing you can do but will only prolong rather than rectify.

I think your next move should be one of them cheap usb boroscopes and have a look in the chassis.
Looking at the spray pattern in the rear door, that is what it is going to be like in the chassis, is shti with next to no coverage.

I must agree with you, I'm no expert but I would not be happy with this result.

Thank you for your replies. A small USB boroscope might not be a bad idea. I contacted the garage again for comment/a solution. Let's hope there is a solution to this.

A squirt a blob here a blob there, mostly in places where it wont help.

l wouldn't worry too much about the axles and differential not being treated, although spraying black wax on them makes them look nice, they don't generally rot (unless someone proves me incorrect) so it's not necessary.

But the back door application is just crap, almost as if the operator was blind, and just sprayed around the general area where they thought the door was.

They managed to pretty much miss the entire door frame - the actual part that will rot!

Usually from the inside out due to condensation ....

Don't give me something else to worry about !!

This reminds me of a film, where 2 chaps were paid to paint a barn or something and it was really high. One of the chaps came up with the idea rather than actually paint it they would just chuck a tennis ball in the paint and throw it up there, they did that a few hundred times and from below it looked like it was painted over the bits that were needed.

The main thing that rustproofing job will do, is cause the Landy to set on fire when you take it in for corrosion repair and they start welding the chassis.
