I used both of these products on the dash and door coverings, and on my leather seats. Meguire's Supreme Shine does a great job giving the plastic and vinyl a nice sheen without the greasy look. It gives it a rich black color and it has UV protection to stop the sun from drying out the interior pieces. It also hides the scuff marks but doesn't seem to remove them completely, and it does a great job removing wax residue on exterior plastic too. Here's some pics of before and after for comparision.













I used Meguire's Leather Condtioner on the leather seats and it really gave them a deep black color. I also used it on the headrests (which seem to be vinyl) and it made them look so much better too. It has UV protection from the hot sun and conditioners to keep the leather soft. Like the Supreme Shine it doesn't look greasy, but it is a little slippery on the seats. I really like both of these products and highly recommend them. Again here's some pics of before and after for comparision.

I did the same this weekend with Adams leather conditioner and got very good results also.

I didn't realize how bad the seats were until I put the conditioner on them. You can see it's a nite and day difference. I'm sure the Adam's products are some of the best, but I've always had good results with Meguire's products.

Mine were bad too. They took the whole bottle, that's how dry they were.

Holy cow, I used about 1/4 of the bottle on my seats, yours must have been dry. I'm gonna go over them again in a couple days after it soaks in.

I need to pick up some conditioner... I have been wanting to but not sure what I should get.. maybe I will try this...

Custom Tails to come eventually, possibly, hopefully!

Wow look great. I got armorall leather from sale last year. I haven't use it yet. I think I'm going to dump armorall and get that one what you have lol I have use lot of Meguire's project like car wash, wax, wheel cleaner and some. I never try interior cleaing product yet. Interior cleaing is mostly from armorall.

_________________

Armorall is bad for the dash, it will cause it to crack over a period of time. Plus it leaves a greasy film on everything you apply it to, so you're better off tossing it in the garbage.

Turtle Wax dash products work well for me. I used some sort of meguiars leather conditioner one time and it didnt do much. it just dried up. I switched to armorall leather conditioner and it works much better but not the best smell

I've been using a mix of Mothers/Meguier's stuff.
My biggest question is what in the hell do you do that gets your seats so dirty? Mine are clean minus the occasional crumb from something.

My car was a rental, that says it all right there. This was the first time I conditioned the leather, so it must have never been done since it was new.

Ahh I understand now. I forgot that you didn't buy it new.
If I bought a previous rental car, I'd scrub the inside of that thing to no end.. our courtsey cars at work get ing..

It was clean inside and under the hood, the Pontiac dealer had it looking like new. But it didn't seem like the leather was ever conditioned so I did it up. I can see it needs another application of it now that it soaked in after a week.

Mine doesn't have a bad smell, maybe you need to replace your cabin air filter. It really should be changed once a year, so mine is probably due since my car was made in 2008.

Mine smells like butthole too. But only usually when the Air Con blowers are on real low...like between 1 to 3. My car generates an awful odor. I DID buy mine brand new....so im kinda lost....lol

(I dont have leather seats....)

_________________

There's a technical service bulletin out to fix the bad smell:

#99-01-39-004C: Air Conditioning Odor (Install Evaporator Core Dryer Kit and Apply Cooling Coil Coating) - (Jun 12, 2009)

Subject: Air Conditioning Odor (Install Evaporator Core Dryer Kit and Apply Cooling Coil Coating)

Models: 1993-2010 GM Passenger Cars and Trucks (Including Saturn)
2010 and Prior HUMMER H2, H3
All Equipped with Air Conditioning

This bulletin is being revised to add the 2009 and 2010 model years. Please discard Corporate Bulletin Number 99-01-39-004B (Section 01 -- HVAC).
Condition

Some customers may comment about musty odors emitted from the Heating, Ventilation and Air Conditioning (HVAC) system at vehicle start-up in hot, humid conditions.
Cause

This condition may be caused by condensate build-up on the evaporator core, which does not evaporate by itself in high humidity conditions. The odor may be the result of microbial growth on the evaporator core. When the blower motor fan is turned on, the microbial growth may release an unpleasant musty odor into the passenger compartment.

There are several other possible sources of a musty odor in a vehicle. A common source is a water leak into the interior of the vehicle or foreign material in the HVAC air distribution system. Follow the procedures in SI for identifying and correcting water leaks and air inlet inspection.

The procedure contained in this bulletin is only applicable if the odor source has been determined to be microbial growth on the evaporator core inside the HVAC module.
Correction

Many vehicles currently incorporate an afterblow function within the HVAC control module software. The afterblow feature, when enabled, employs the HVAC blower fan to dry the evaporator after vehicle shut down and this function will inhibit microbial growth. Technicians are to confirm that the customer concern is evaporator core odor and that the vehicle has the imbedded afterblow feature, as defined in the SI document for that specific vehicle model, model year and specific HVAC option. Refer to SI for enabling the afterblow function. Vehicles being delivered in areas prone to high humidity conditions may benefit from having the afterblow enabled calibration installed prior to any customer comment.

hmmm....That sounds like my problem...Minus the high Humidity thing. I think i will have them look into it when i have them rebuild my front right suspension and replace the front bumper cover (Hopefully with a GXP one! (The manager of the body shop said he could probably do that))
