Hello, I would like to use a pre-cleaner this time before the wax application. As a wax I take the “Petzoldts Premium Wax” as always: http://www.petzoldts.de/…/…Premium wax set,-Carnauba-p-1499.html The MFT is already there. From the FAQ I have chosen the “Excellent Amigo” as pre-cleaner, which has received very good reviews. A few questions: – Can I use this Petzoldts sponge as an order sponge for the Prima Amigo, namely http://www.petzoldts.de/…/. .tragsschwamm,-round,-2-layer-p-1519.html That would be the same as with the wax. – Must the sponge always be moist for the Prima Amigo or can I apply the pre-cleaner as well? – How productive is Prima Amigo ? I mean to have read that 3-4 drops on the pad already suffice for an area of 50×50 cm. – Can you use Prima Amigo also for aluminum rims ? – Contains Prima Amigo abrasive ? What else to consider when using the product ? The varnish is “phantom black pearl effect” and now almost 7 years old. Up to now only with wax was worked every year without the use of a pre-cleaner, see picture. Thank you already in advance.
