Hello Everyone,

My 2009 pre-facelift Galaxy Grey 2L Tech Sport is only used on dry, salt free roads in the 'UK Summer', whatever that is! Always garaged and much loved. Done less than 41k so far. Imagine my horror at finding rot underneath the rear crash structure. Had the structure grit blasted and coated and the shell sanded and painted before refit. As a result I've decided to undertake a more intense search for iron oxide. Now had to replace the window guides with post facelift 'protected' versions as they were corroded adjacent to the rubbers. Dinitrolled inside of doors whilst they were apart. On axle stands a present, about to clean and coat everything I can reach. What should I be looking for?

Thanks to anyone who helps

Gosh, on a summer car?

Have you done your drain holes often?
Fingers crossed you’ve got the worse of it

Welcome to our little corner, antioxide. :wave:

You're iron oxide won't be too difficult to find. Mazda are well known for the lack of body protection im afraid.

Welcome to the forum antioxide.   In addition to all the bits you can reach , get some dinitrol into the inside of all the box sections including sills.

Thanks for the welcoming words.

 

I had read and heard the many tales of Miata corrosion woe but this discovery was truly shocking. Anyone who designs a structure that involves bolting two bare metal items together BEFORE they're painted should be tied a post and shot.

 

Enclose pic of fix.

 

Found an oboe brush (?) that keeps the hood plumbing free of crud. On another topic, although I think I'm a reasonably clean human being, the seat belt rewind started to require assistance in order to avoid being trapped by the door. Dirty belts? I spent half a day using buckets of hot water and laundry detergent. Oh yes, and a hair dryer. It worked.

That has come up many times, JD, silicon spray can help too. I know many have used that. A quick wipe with a rag after spraying though I'd imagine. ;)

Hi and welcome to the forum :)

 

I am a member of a group for 25th Anniversary owners, and rusty rear crash bars is a recurring problem, even on low mileage cars owned from new, and they were all registered in 2014! :eek:

Hi Paulo and Wrangler,

Almost from new. It had a brief existance as a second/Sunday car with a lady owner remotely known to me. I'd been looking for a rag top Miata with an LSD and Bilsteins as a project /toy for a while. As a bonus this came with a factory removable hard top. The colour was not my first choice, I had been looking for Copper Red but this car appeared just a few miles from home and was too good to miss. Becoming a pensioner and being bound by the lockdown has finally given me the time to do the upgrades I've been planning over the past many years! Engine, brakes, bushes, cooling, wheels and more. No plans for track days, just more grunt (with brakes to match) and further handling improvements. Only driving boxes to tick are the NC500 and a road trip to the Med coast with my wife and minimal luggage!

 

Nice to hear from the North Star State. Restrictions permitting we'll be visiting friends in Minnetonka and Minneapolis-Saint Paul as soon as we can. Knowing the local weather I guess your Landy and Frontier get most of the work, or do you have chains on the Miata? We have an upholstered wheelbarrow called a Toyota Hilux Invincible (Tacoma in USA) to do the heavy lifting. I've recently been shopping with Flyin' Miata. Nice people - do you use them?

Before the Nissan, I had a Toyota Tacoma, which I always referred to as a toaster. The Landy has not been on the road for years, since I damaged my shoulder off roading on a bicycle.  So when the roads get totally covered with snow, the Nissan is the go to machine. My MX5 is my normal vehicle of choice. I use all season tires, which allow negotiating up to 3” of snow. I have not used Flyin' Miata, as my car is as new from the factory, and Moss Motors has been able to supply the few bits that I have required. 
 

I know Minnetonka, and also have friends living there. Our daughter lives in Minneapolis, and works in St. Paul. With the Pandemic, we have not been to her house in over a year. Our home is located 100 miles west of Minneapolis, so it is a small jaunt to visit.

Hi Anti.... :wave:

 

Welcome to the 'Life' madhouse ...errr sorry forum I meant!  :nod:

Sorry you have discovered probably the two worst things on the Mk3, as others said rust protection isn't good on the Mx...

Other thing you might have issues with is the 4-wheel alignment the Mk3 wasn't perfect 'out of the box'.....and quite often the handling can be much improved having it set up properly!

Anyway, enjoy....I'm sure you will, and come back and tell us about it!

 

Take care.
