It's ok as long as u do it in a sheltered area. Cos it will just dry out too quick and will end up looking **** to be honest mate.
That's y I drove to local carpark and paid for a day ticket and done there lol
Sad as it sounds but in the shade is the only place to clay mate.
Nice work. However not a job I would do myself, too lazy and would gladly pay someone to do such a job when the time comes. Hats off to you for such a great job. It looks showroom.
