I have some mother 3 step left, do you guy think I should wax on my one year old car?? I ask that because I paid over$300 to do the wax and underbody thing when I bought my car. I don't want that step 1 wax cleaner clean all my expensive wax away.
Is is okey to use 3 steps on my car??

 

If you're THAT worried about your $300 wax then just apply step 3 of the 3-step system. Step 3 has no cleaners whatsoever (well maybe a solute to keep the wax in solution..whatever) so you should be fine.

You don't HAVE to apply steps 1 and 2....they only help to enhance the shine of the entire system.

Your expensive wax is most likely a polymer based wax that the dealer (or some aftermarket company) sprayed on your car. You can go over it with the step 3 "pure" carnauba with no problems.
