Looking good

Love this thread. Great car and everything you do is tasteful! Nice work.

I noticed when reassembling the car, the number plate LEDs were failing/flickering. When pulling them out a few circuit board thingys just crumbled away..
Time for a some new ones:

The side reflectors were painted using the left over paint from the wing, what a difference having them painted has made, It looks much sleeker now, those reflectors really stood out (actually, I can't blame them, that's what they're supposed to do )

Thanks.

Looks better with the reflectors painted. Are they easy to get out?

yeah, wheel off, loosen the inner arch liner, bend/push it back, get a 10mm socket in there.
Or get behind the access panels in the arch liner. A mixture of the both methods will sort them.
They're a self tapping nut on a plastic prong, 2 per side. Exact same as front BMW badge.

I used double-sided foam tape to put them back in, but once I'm next in that area, I'll put the nuts back.

Cheers. There is a load of crap in and around mine and I think it’ll be easier to clean it up with them removed.

The last few weeks have seen very slow progress with rust proofing the nearside.

Last month I replaced the offside rear arch and treated the length of the sill seam and also inside the front arch, it was time to tackle the nearside.
I have no visible bubbling but I wanted to get under there to see what was lurking.

I wasn't planning to remove any arches, just inspect and treat what I can see.

I was expecting the nearside to be much worse, as are most cars due to more puddles and dirt on the gutter side of the road.

The inside of the panels were in excellent condition.. Far better than the offside. Quite surprising, really.
Inside the rear arch, where it meets the sill cover, does have some very minor blistering but nothing like the other side did before I replaced it.
The sill seam was a little crusty, but really nothing to worry about.

Day 1 was removecall trims, scrub and scratch away any loose crusty bits. Then apply Bilt Hamber Hydrate 80 to the inner arch lips and as far along I could reach along the bottom of the arches where they join the sill cover and bumpers.
Also the length of the sill seam.
Hydrate 80 converts existing rust and forms a hard barrier over the top, ready for paint or underseal.
Day 3 was rattle can primer but painted on with a brush.
Day 4 was rattle can clear coat but brushed on.
Day 5 was black underseal, painted on. This sets hard after day or so.
Day 6 was reassemble the arch liners and sill panel.



That's now both sides treated, along with a new rear nearside arch (that I also undersealed)

By no means a professional job (apart from painting the new rear arch) but much care was taken with preparation and application so I'd like to hope I've held back any corrosion for a good few years to come.

The sheer number of brands and products is overwhelming, also the process, what's wrong, what's right. It was a nightmare trying to find the correct option.
I just went simple and got a converter which also forms a barrier, that can then be covered (although apparently its optional) with paint/underseal.

[STC_Zed]

Good work.

Yeah, there are definitely are lot of products out there. Hydrate 80 does seem to be rated very highly.

I’m going to have to get some paint done on mine in the spring due to a few bubbles.

Great to see the old girl looking so well
Did you ever get the passenger front wing off? I was always convinced it had had a small repair at some point early in its life - perhaps a parking knock and a smart repair - just wondered if there was any evidence on the inside face of the wing?

Hey Sean.
Yes, she's in great shape. Sorting all these age related issues has been keeping me busy.
I didn't bother to remove the panels, after completing that process on the drivers side, I really didnt fancy it again.
If I'd have found horrors inside I would have continued to remove them and treat, though.

With the wheel arch liners out and the car up in the air I was able to get underneath for a real good look. There's nothing obvious inside at all.
But it's clear the front passenger wing has been painted, the base colour coat looks 'flatter' than the other panels, underneath the clear coat.
And around the 3.0si badge I can see some contamination that must have appeared during the paint process, too.

I'm happy to live with that, especially as I know the inside is now clean and protected, that's the important thing. The paint job really isn't that noticeable.
If I'm feeling keen in the future, I'll take it to my paint man for a re-paint.

Awesome looking coupe! Nice mods everyway.

Thats brakes looks totally awesome!

[Meds]

Thanks, yes, the car is in a good place now.
I took it for a proper, extended drive the other night and it was flawless. Exhaust note is perfect, ride height is spot on and everything works well together.
It doesnt get used much, just to the shops and back, so the opportunity for a 'proper' drive is always welcome.

Who doesn't love a clean engine bay?:









For those interested, all plastic surfaces, hoses and pipes had a soapy sponge/brush then treated with CarPro Pearl 1:2.
I hadn't realised how grey everything was until treatment, it's made a huge difference.
