OK, This doesn't rate up there with installing a lift or a SAS.

I was cleaning the interior of my '99 when I noticed that the plastic shield in front of the spedometer and tachometer was looking really tired. It was scratched from wiping 8 years of dust away and dirt.

I took some Meguirs Plast-X plastic polish and gave it a 2 minute polish. Holy Moly! The scratches disappeared. Seriously, it's so clear you can't ever tell it's there. It makes the dash look like a new car.

 

That's awesome. I love the little things that make you so happy once you do them. I changed my o2 sensor the other day and now the 5VZ-FE runs like brand new even with 200k mi on the odometer. I didn't know it could be so smooth!
