Thought I'd give this 'hard' wax a try, as it is specifically made for white/silver cars??
Arrived within 3 days...small pot, says can wax 3-4 cars, smells vanilla-ish, not bad..tried it on the bonnet area to start with-yes the wax is VERY hard & you need to warm up if possible(bit like trying to get cheddar cheese onto a cloth..)But I must admit, it went on well-used hardly any-hardly any residue...& looks really brilliant to be honest.
It would probably stretch to 3 cars waxing, & you do spend a lot of time trying to get the stuff out of the pot-but 3 weeks after waxing the car, it still beads & looks awesome..after 2500 miles!
Not cheap-but does work-presume it's the 'tester pot'.
In fact the pot looks & smells so good, my friends 12 year old did use it as lip gloss..result!
