Hi there. I hope I don't posting this in an incorrecto forum.

Greetings for everybody in the forum from México.

I have a Dodge Neon with the standard black coated steel rims/plastic silver coated combination and I don't know if the green APC from Meguiars could promote harming or coat falling in a dillution 3:1, 4:1 or even straight through by the time. I actually use a little of the Shampoo for the paint (Meg's UW&W or NXT) but I could try using the Megs APC to clean wheels and wells faster and with less effort than the shampoo and brush method.

Do you mind if you give me some advice to clean this area of the car?

Also, I was wondering if there is some product to clean the black plastic of the grille, it seems to have water spots/old dry soaps and bad quality moisturizers residues with an opaque look. If this APC works for this, what dillution ratio could I use? If not, Which product is the best for this purpose?

Thanks in advance for your support.
