Last week I applied 2 coats of Z-5 followed by Z-6. I then applied two coats of Z-3 followed by anouther coat of Z-5. I drove the car for the week and on Friday night I rewashed it and applied Z-8. I applied it in my garage, and when I was done it looked great. Today I took it out in direct sunlight and it wa loaded with smears. I reapplied it tosome parts, but still had smears. I used a 100% cotton made in the USA towel. Any suggestions?

 

The only thing I could suggest is using LESS of the Z8 next time. As I understand it, Z6 and (I assume) Z8 are both HIGHLY CONCENTRATED and no more than 1 oz is good for an average sized car per application/coat.
I applied 3 coats of Z5 today and applied Z6 inbetween each coat. I still managed to only use approx. 1.5~2 oz. of the Z6 and 2 oz of the Z5.

So, I would suggest washing your vehicle once more re-apply using less Z8.



Hope this helps.

 

If Z-8 should ever streak,... Just wipe the area wipe a damp towel and
the streaks will disappear.

Z-8 is extremely concentrated, less than 1/2 ounce will do the whole car. You are applying way too much. Remember less is better with Z-8...
