A ceramic coating is the best such as c5 (which is also the same as c1 and c4 confusingly)
Waxes never really last as long often because of the extreme conditions they are put through. Very high temperature followed by rapid cooling. Waxes can not really deal with that.
Not true at all.
I tested FK1000P against a C5 that I bought off Richwig on here. I put the FK1000p on one front wheel and C5 on the other. I went away for 8 months and my wife was instructed on how to clean the wheels. Basically she PW rinsed them and the car once a week (over winter).
When I came back both were still protecting the wheels and both to the same extent. I.E similar beading and ease of cleaning.
No doubt if you were to get the microscope out then the C5 may well be doing something better. But in the real world FK1000p performs just as well if not better.
The thing about FK is the ease of application & removal. You can coat all 4 wheels at once (assuming you have a lift or 2 at once if using axle stands) let it cure for 30-60 mins depending on the weather. Then buff off. I always apply 2 coats to ensure full coverage.
C5 is a pain to apply as you have to apply it a sector at a time and buff off straight away or it crystallises. I did a quarter of the wheel at a time. I left it 24hrs and put on another coat (to ensure coverage & fairness for the test)
Don't believe all the hype you read online especially when it comes to detailing. Something I learnt quite quickly. GTechniq make some good products, I have C1, C4, C5 (yes I know they are all the same), C2v3, C1.5v2, G1, G2, G4, G5 & I1 (which is very good stuff)
But there are other products out there that perform just as well and in some cases better. A lot of it is in the eye of the person who has the product. Especially if they have bought it.
FK1000p is a high temp resistant paste sealant. The main decisive factor for me is that it performs just as good as C1,4,5 and will last a few years as the tin is hooooooge.
