I have rather deep key mark (show primer) and a few fine scratch on my new blue car. As it said on the directions if you have deep scratch you need to get the match paint for it. so we went over to Wal mart and get one of those 5 dollar repair paint that come with a small brush and ball pen in same bottle (they come in several known brand and color such as TOYOTA , FORD, GM, etc I also saw the same products at Kregen too.

First i wipe clean the surface with wet cloth and then very lightly wet sand to smooth it up with the sand paper provided it in the kit then wipe clean, The sand paper is 3000 grid which is very fine and did a good job for it's purpose. I like it much better than the 2000 grid one they sell at automotive store. Only if they give you more than just a few strips i will be alot happier.

Then I use the brush side to paint on the bigger scratch area and use the ball pen for finer line. Let dry for few hours. And to make sure i really fill those scratch well I re apply the paint and let dry.

After the paint completely dry use wet sand to very gently sand the excess paint off ( this part scared me the most because they said it very clear not to expose the primer, So take your time and be very gentle). When you are done with sanding the scratch should feel very smooth to the touch. It still look very visible but after i use cream no. 1 (buff hard) it look better so i decided to do it again twice. After 3 applications of cream no.1 and finished it with cream no.2 the scratch almost disappear. I still can see it a little but i know where to look for it. It does not take away the scratch completely but did improve and lighten alot. I think it's reasonable enough for it's price. If they sell this for 100 dollar then i will expect much better result.
