Ok, as promised - I hit the trusty old Passat with the Ultima today.
This is a 3 year old car, stays outside 24x7, has previously been polished using swirlbuster polish and pad from Autopia, and finished with Klasse AIO.
This car had had a few weeks of sprinkler spray down one side, and the AIO had definitely warn off!
So usual wash & dry, then a full clay using Meguires pro clay and speed detailer as lube.
After the clay, the process was the same as for the Boxster last week.
Piant prep + a Panel at a time - wipe off the polish before it dries on the car (learned from the Boxster)
Did the whole car with the polish, then applied the trim sealant on the black, and the paint sealant on the paintwork.
Again, easy to apply, no real streaking issues - just a thin thin coat as before.
Gave it a slight buff after 1 Hr, and then just left to cure.
Results:
I'm sold - paint looks great - smooth and deep gloss.
Trim went nice and black - we'll see how it lasts outside!
