Hi mate.
Not allowed to say who I am lol or the scary admin people will come knocking again
however I know about CarPro finest
anyway can I ask when Finest was applied, wasn't long ago was it?
Finest is a ceramic sealant coating. The coating needs to be kept very clean to keep up its beading appearance. Also remember sealants dont bead like wax, they sheet water.
Although it isn't beading, this isn't a indication the sealant is not their. Finest will last two years minimum if applied correctly (which if Russ done it it will be) and maintained correctly.
so onto maintenance, Normal washing routine should be, jet blast, pre-wash cleaner/snow foam (if tou have it)then two bucket wash with a pure shampoo and lambs wool mitt. what this means is not with gloss enhancers, carnuba etc etc. simply dry and do not add any qd or similar. Adding wax, qd, gloss enhancing shampoos massively effects the water behaviour.
next time you wash it and give it it's final rinse, observe its water behaviour. Use an open ended hose. The water should bead in places but mainly 'sheet' of the panel to leave it near dry.
If it doesnt There is two things you can do here. Firstly as mentioned it needs to be free of contaminants. Every so often give it a fairy liquid wash. I know this goes against all what detailing tells you but it will clean the sealant of nasties. This would normally remove waxes or normal sealants but finest is alot tougher!
Secondly I would massively encourage you to buy CarPro reload. It is the top up for all their sealants and is superb. This will bring back all the beading and sheeting and further protect the coating. It will also look the shizle
Being that your colour is performance blue or whatever ford call it now, you may need to dilute reload slightly with de-ionised water. It can sometime be a little smeary/cloudy on darks.
to use, once washed, dry the ST and spray once per panel ish in a long sweeping movement. Sometimes you may need a little more dependant on size. A little is all you need. Using a new/soft MF towel spread it around untill it disappears. Job done!
Finest is defo the future and out of all the sealants, nano ceramics and waxes I have used it is the best!
let us know how you get on
