I have used KAIO on smooth plastic finish before and it's amazing! Never thought about topping it with KSG though! It does make sense!! I am going to use it on my Tundra next time I do the bumpers and stuff to see how it looks. Thanks for the tip!!
Instead of going through the steps that the rest of the paint took I used Poli Seal on it. It removed a lot of the visible swirling and gave it a coat of protection at the same time. It's a lot of work figuring out how to get up there, balance on whatever you are standing on and polishing/waxing at the same time.....

I am too big to hit the ground that hard!! LOL!!
