You missed the fact that it's 400 gram
Double of tonyin 200g
So in apple apple 200g comparison, 400g nu finish costs 2250 and half is 1125
So 1125 vs 850
It's 275 rs difference
I have used both
Car is daily driven, 250-275kms a week
Tonyin 2 coats lasts for approx 2.5-3 weeks
And nu finish 2 coats have crossed 5 month mark
Here is water beading after 4 month mark
It was still strong even at 4th month considering its cost
Now 5th month is about to end and it has started showing weakness with 6th month start
Beading has weakened a bit but sheeting is there
So I'm waiting for it to break down on its own rather than stripping it off for another product
And it exceeded my expectations in longevity dept considering cost
Tonyin crap is no where near it
Initially I planned to just use it once and sell the remaining but after this experience I'm planning to finish it on my own car, with 4 coats every year, 2 coats every 6 months
