Re: polishing and or waxing
I use Mer, which is a liquid cleaner and wax. Back in the day it could only be found at markets, with a Del-Boy character demo-ing it on an old mini bonnet, and at independent small auto factors, somewhere hidden up on a shelf.
Now it appears to have gone upmarket and I picked some up in Halfords, and I think it's also on Amazon.de.
The familiar sky-blue bottle has also turned black.
There are two recommended methods of use:
- periodically, apply neat on a damp sponge, allow to become powder-dry and then buff-up;
- more frequently, add a couple of cap-fulls to warm water and clean the car with a sponge, dry off with a chamois or equivalent and buff-up with a dry cloth if required.
For starters, I would pressure wash, then use the dilution washing method, followed by the neat method; and then continually with dilution method regularly interspersed with the neat application method, a little less often.
Frequency and regularity are the key - Del-Boy at the market had polished his mini bonnet so many times, that he used to empty a can of liquid lighter fuel over it and set it alight. He would let it burn completely out and there wouldn't be a mark on the paintwork ...... because it had been polished hundreds of times.
Mer works really well to remove oil, tar, caked-on and sun-dried birds' crap and most of road mess.
When used neat, on light scratches, it also works similarly to T-Cut, by blending-in the paint colour.
