Carpro Cquartz 30 ml Kit

The Carpro Cquartz 30 Ml. Kit unboxed. Includes applicator, 5 suede clothes, 2 stickers, and 30 ml of Cquartz.

Cquartz is very easily to apply.

• Wrap the applicator with a suede cloth, apply a few drops of Cquartz to the applicator and wipe onto surface.  
• Let Cquartz cure for around 20 minutes and wipe off with a microfiber cloth

The 30ml kit is enough for a mid-size sedan, for multiple coats and larger vehicles go with the Carpro Cquartz 50 Ml, please note this does not come with the block + cloths.

Many users have reported Cquartz lasting over one year and up to two years, to me it is well worth the price.

Cleaning & Polishing Exhaust Tips - BMW 428i

Regularly clean exhaust tips to prevent corrosion, pitting, and discolor.

Here is a look at the exhaust tips on a 2015 BMW 428i M Sport. The stainless steel tips are in need of some serious polishing after a few thousand miles of driving.

Spray exhaust tips down with Optimum Power Clean - 17 oz. at a 3:1 to 5:1 ratio. OPC is full strength so you will need to dilute it in a spray bottle. I use Kwazar Mercury Pro+ 1 Liter Spray Bottle because it is a dual action trigger.

Scrub the tips down with a microfiber towel and some soft brushes. Once the dirt and grime is gone, wipe the tips with another microfiber towel.

Grab some Red Devil 0000 Super Fine Steel Wool and some Optimum Metal Polish 8oz or Optimum Power Clean - 17 oz. and scrub the inside of the tips.

For the outside of the tips, use Optimum Metal Polish 8oz and an old microfiber towels to polish. Be careful not to use too much force, you do not want to polish through the finish.

After pictures in one pass.

Not too bad after one pass. Exhaust tips look better after several passes and only look shinier with regular cleaning.

One thing to note is dust seems to build up pretty quickly with all the rubbing and static electricity.
