So the wife's car has been suffering a shithouse electrical issue that basically ment that the car could break down at any time. In fact, it happened 3 times with really bad timing. So the wife said enough was enough and we needed a new wip. We checked out the usual SUVs and almost bought a Kia. NEK MINUTE we bought this black thing.

Surprisingly neither of us actually wanted a black car - too hard to keep clean. So I did.some research.into coatings and ordered a DIY ceramic coating of Gyeon MOHS2 which has just landed at my place. This weekend will be spent applying the coat

I also scored this mazdaspeed spoiler off gumtree. From the photos it looks like th real deal! I'll know.more when I get it.to my place.

I'm amassing a few bits a pieces to make the car look better. Still want to find a chin spoiler and maybe eyelids. They're a bit wankish usually but not too bad on an RX8 as per below image

Cars going to an auto elect tomorrow,.I've given.up on diagnosing a drain the the battery. I suspect it's linked to the head unit or amps.

My wife bought me a new polisher for father's day so I made good use of it over the weekend and gave the car a good cleanup. It's been a year since I polished the car last.

To start, I washed the car with a car wash (no wax) and dish washing liquid. The dishwashing liquid strips the wax off the car showing how truly bad the paint is. I noticed that's have a area of crows feet on the bonnet tester size of a 50cent piece. Absolutely devastated. I'll have to repaint the bonnet later. I also noticed how bad the scratches in my clear coat are. It changed my whole plan for the weekend! I was going to put a ceramic coating on but realised I'd be wasting my time. New plan, do a wax coating.

First step was a clay bar. As I did this a year ago, it came up pretty clean. I then used the new polisher and Maguires compound for cutting. after a test run I noticed it barely made a difference. I found a cheap cutting compound I had at home and tried that too with more speed and laps over the panel. It was better but the marks were too deep. I may use a 2000grit sandpaper on the car next time.

After the cut, I used mothers polish. After the polish I used a Maguire canaba wax.

It came up a lot better in the end but the crows feet, stone chips and deep scratches have left me feeling disappointed in the finish. I think I'll be repainting a few panels in future.

The plan was to use Gyeon Mohs on the carImage

DONT wetsand. Mazda paint is notoriously thin from the factory. You are lucky to have 80 micron average over the car. To put that into perspectuve most professional detailers will stop heavy correction at anything under 100micron. Im currently sitting average 50 micron.

At most a medium compound with heavy polishing pad is enough on the soft black to remove almost all defects in a single pass. If you have any remaining 90% of the time its due to the microfiber cloth putting them back in during the compound removal.

The Rocky is a good machine to start with. Adequate power just loud and vibrates alot. Once you learn a bit more you will move onto better products and more effective compounds than you can get at the local Supercheap.

Gyon Mohs is a decent coating too. Nice choice. Difficult to apply evenly but a nice finish.

Thanks Bob. I remember reading about the lack of clear coat for Mazda. I'll avoid the wet sand then.

I used a high pile microfiber towel. The scratches were already there, way too deep for the compound to have caused. The last owner must have washed it with the worst sponge he had, as the marks are across every panel. I use the two bucket and mitt method and a foam lance.

Can you recommend a good compound? I used what I had laying around.

The Gyeon stuff is amazing. I coated the wife's car in it. The application was.easy but took me 2 full days to apply. I then did a coat of Cure and Wetcoat. I've never seen water bead off a car like their products do. Only problem is that after you pressure was the car, it's already dry again!

This stuff is amazing. You spray it on after washing the car and just pressure wash it off. It has a hydrophobic element to it and makes the water bead straight off the car. Ive used it on two cars now and will be using it on the RX8 after the next wash.

For our paint HD Polish and HD Adapt are great products and wont stick. Couple them with some quality HD Red foam for the polish and HD Green polishing pad for the Adapt. This combo can tackle just about any situation you come across on your own car

My engine has been experiencing hot start issues recently which I put down to old age. The car has 120k on it and as far an I'm aware it's the original engine.

Before I set off on a path to rebuild I'm giving the engine the seafoam treatment. I followed the procedure set out on rx8 club which is as follows:
1. disconnect eshaft sensor and air pump
2. Plug in hose to vacuum nipple and connect to engine cleaner - I used 5mm clear hose.
3. Crank engine of 10 seconds. Do this twice per chamber.
4. Wait an hour.
5. Add 2 stroke oil to vacuum line and crank engine for 5 seconds per chamber. ( I skipped this and used wd40).
6. Connect eshaft sensor and air pump.
7. Start engine.
8. Rev to 6krpm ~20 times and smoke out the street.

I did this at the in laws place resulting in a few people driving past very slowly and staring. Mother in law though my car caught fire. The smoke was much worse then the photos suggest.

After 10 minutes of running the smoke mostly cleared. I switched off the car and let it rest for 10 minutes, started the car again and it cranked over instantly - no hot start issue. I'll be changing the spark plugs next and doing a compression test next.

Hmm not a lot of activity on here. Fortunately I've been a little busy buying stuff for the car. One thing that has become very clear is that the engine in my car it's nearing end of life. I plan on doing a rebuild next year and will start amassing parts for the build. I want to do a street port or maybe a half bridge of I can DIY it from a template. I may try a light flywheel too.

Moving on... I've bought a new (used) exhaust, rear mazdaspeed spoiler and now a front chin spoiler. All of them need some type of work which I'm happy to do.

SPOILER: its a fake. On close inspection, the brackets on the spoiler which I think are supposed to be aluminium are actually fiberglass. One of the bolts to the boot lid sits off centre and the trailing edge is not very straight.

The plan is to plug the hole in the base to redrill, clean up the trailing edge and paint the whole thing including the boot lid it came with. I don't want to drill holes in my perfectly good boot.

EXHAUST: this was kinda a sight unseen purchase. The exhaust was advertised as a full exhaust with headers, unknown cat and an Xforce 2.5" - 3" stainless exhaust. When it arrived I understood what they ment by the change in size.

The force exhaust is a 3" system that bolts up to the end of the Cat pipe. The mazda cat pipe is 2.5 standard. For some reason, the last owner swapped out the Cat, deleted the resonator and bunged on a 2.5 pipe where the xforce usually bolts to the mid pipe! Makes no sense.

I've given the exhaust a polish and went on to install the exhaust as is. When removing the old system I expected to see a clogged and melted cat based on the fact that the fumes are crazy and I have no CEL. What I found was a surprise. There was no honeycomb in the Cat at all. It was completed clean. I have no idea how it never threw a CEL. After the install I had a bad exhaust leak at the join between the manifold and the Cat pipe. As it turns out, I forgot to install the metal ring gasket. This has now been remedied. The result is the the new exhaust is about the same volume as the standard system. I'll have to install the headers and replace the 2.5" section with a 3". It needs to be louder.

I also painted the headers black as it didn't respond well to polishing.
