2019 Part 4

Postby njonesn » Thu Nov 07, 2019 12:06 am

So earlier in the year I took my car to get a 'full' rust and underseal treatment.
The garage I took the car to came recommended, had treated other MX-5s before and showed them on their site.
As it transpires the job was not very complete. Parts were not removed so underseal was missing behind some sections and known areas of rust were not treated.
In short not much was done other than rust treating and undersealing the underside of the car. Saved me a dirty job but was expensive for what it was. Expensive lesson learned!
M-m has documented my, and others, experiences on the link below so I am not going to repeat that here.
http://www.mazdamenders.net/forum/viewtopic.php?f=38&t=7521

Since then, following the amazing guidance that Mazda Mender has detailed on that thread and directly (thanks so much M-m), I have set to putting right what was missed.
This is not complete yet and I will post updates as I progress.

I have got the car on stands, removed the wheel liners, pulled back the front arches (in fact I ended up removing them because its easy and I'll get a better job done) and cleaned everything up.

I inspected the rear sills by removing the rubber grommet behind the rear wheel liner.
Was pleased to see that there was not much rust. Initially I thought it looked bad however that turned out to be very dry dirt (I expect the drain hoses were blocked at some point).
I cleaned out the sills using a host attached to a handheld hoover.

I then injected an entire can of Dintrol RC900 into the sills via the holes behind the rear arch liner and the B pillars (as seen in M-m's guide linked above).

I left this for a week to dry.
While it was drying I undersealed everything that was missed by the garage.

I then set to injecting cavity wax again following M-m's guide.
This is how the rear sills look now, of course I have cavity waxed the box sections etc. as seen in the guide.

I have cleaned up the rust on the back of the passenger side wing and treated it with rust converter.
Next is to give this an undercoat and then underseal the back of the wing.
Drivers side will be put back as is until the spring when I will get the new wing painted and fitted.
That is where I am at currently. Other than finishing the underseal etc. I will be changing the fuel filter while the car us on stands

Next spring I am planning on getting the chassis rails cut out and repair sections welded in.
I inspected them earlier this year and although the rust is not bad yet on the outside they are blown on the inside so need replacing.

Rear bumper removed and two coats of underseal applied behind it. Once that’s gone off I can put the bumper back on.
Removed the muffler heat shield and undersealed the boot section hidden by the heat shield. Will clean up the shield before replacing.
Stripped the front ready for a clean and underseal.
Could get a proper look at my chassis rails too. As I already knew they are past their best, seen a lot worse though, and need cutting out (happening in the spring).
I think there is only one bit left now that I want to remove and underseal behind, mid-section heat shield.
