Wow great answer from Seckin and I totally agree! Other alternatives
you can look at is Fast Wax by Malco/Presta. They are breathable paint
protectants, not a polish like M80, so could be better suited for your
needs since your main concern is protection. Claying should be fine as
long as you use a body shop safe spray lubricant.
To be safe just use water or with a little bit of shampoo mixed in.
Professional polishes are usually body shop safe, i.e., paintable/
breathable, if you are using an OTC "polish" however, they may contain
waxes and will seal in the paint, preventing it to fully cure. Then
again, my test panel has been waxed immediately after painting(with no
ill-effects), and the body shop guy says can be waxed straight away,
but most online resources say have to leave for 1-2 months. To be
safe, leave it for 1 month.
If you are unsure whether the product that you intend to use is body
shop safe or not, or do not have access to a body shop safe/breathable
polish/wax, then just wash it frequently, like twice a week. The paint
should still look new until the end of the month.
After that, you can give it the full monty...
