I'm having a doubt about the real effectiveness of color waxes.I have a black bike and was applying the black colored wax when I started thinking about its effectiveness since the black paint has a clear coat ,the black product is being applied to the aforementioned coat and not to the black paint underneath.Is my reasoning right?Thanks.

 

Yes and no. The pigmented wax helps to hide the scratches in the clear. How? It keeps the black paint from reflecting them back at you. I have a black bike as well and the black wax works really good.

 

The other thing it's good for is non-clear coated paintjobs, and old, old paint where oxidation has set in.

 

I'd suspect that after you use it too many times,you"ll realize there's a build up of that stuff on your paint,and it will not look so good. It happened to me with a wax with 'teflon' in it.When I realized the bike didn't look such a deep black any more,I had to solvent wash it,and wet sand and buff it.
Actually,I haven't used wax for years,I use polish only,on my bikes and my show car.[and my driver pickup,during its semi-annual cleanup!]

 

The only way to really get your paint corrected is with a buffer and an abrasive product. The gentler the product the better. You will have to choose a product based on the amount of correction needed.

This is not nearly as difficult as it sounds. I bought a Dual action Polisher last Summer and did my Bike and what a difference... it was a little time consuming but not difficult.

 

I'm going for the grunge look.
