Having a fair bit of time on my hands recently I decided to apply a PTFE coating to my dreaded Black Pearlescent Voyager.
Black is beautiful if you clean it and leave it in your garage (my garage is too small for the bus).
I HATE CLEANING CARS.
So, having bought this sealant a few months ago, I finally opened the bottle and armed with a mass of microfibre cloths commenced this dreaded operation.
So panel by panel applied the first coat (reactive agent ?), left it dry, buffed it off, applied the PTFE top coat stood back to admire the result (clean and shinny) and proceeded to the next panel.
After completing half the vehicle, went indoors for a coffee and decided enough was enough for the day. A couple of days later (slow to recuperate) decided that it wasn't going to finish itself.
In the meantime I went into town to get some essentials (as per HM govs rules) - I consider cream cakes part of my 5 a day, and noticed rain spots from the previous day still on the bonnet, so it's not magic but as the bottles were open and already paid for decided to carry on and complete the task. The last panel was the roof, and being 6'5" still needed to open the doors and stand with feet in the car to reach the centre of the roof.
Please note that pigeons know exactly what you're doing and therefore shat all over the roof - despite Chris Packham's crusade I'd love a shotgun!
Regarding those rain spots, they didn't wipe off with a dry rag so had to wash them off - not difficult but thought this would be a thing of the past.
Anyway, will see how things go.
