Please excuse my ignorance but how does this work?! Haven't you've ended up with nice black paint where there previously wasn't any paint? I've never understood how this works.
Collinite 476s gets my vote for wax once you've finished the polishing, and make sure you're not using a sponge to wash the car (or a garden broom as I have known to happen
) or you'll likely damage the paintwork and undo all your/the detailer's hard work.
At a guess...... the spoiler was bonded on to the boot and the damage to the paint work was done when the spoiler was removed.
Provided a scratch isn't right through the clear coat it can usually be removed or reduced to a point where it's not as visible.
Polishing removes a small amount of the clear coat around the scratch which reduces the depth of the scratch and rounds off the sharp edges that catch the light and make the damage visible.
There is only so much correction you can do as you will eventually run out of clear coat
(although you would have to use pretty aggresive products to do this on most cars)
As a general rule, if you can feel a scratch with your finger nail then it's probably too deep to polish out BUT you can usually make it look better
As for using sponges on cars...... I physically shudder when I see them being used
You see someone with a brand new car thinking they're doing the right thing by cleaning it regularly with washing up liquid and a sponge :shake:
IMO, the safest way to wash a car is using the two bucket method:
1 bucket of car shampoo
1 bucket of clean water (and a
grit guard is even better)
Lambswool wash mit (although synthetic/microfibre mitt isn't too bad)
The technique would be to rince the car down using low pressure then starting with the roof cleaning a panel at a time working down and round the car.
Load the wash mitt with shampoo, clean a panel using long strokes (not circular), rinse the wash mitt in the clean bucket, load with shampoo again and move on to the next panel.
If it's a warm day, rinse panels as you clean them and ensure they don't dry out before you're ready to do your final rinse.
If the car's particularly dirty, you may want to use a separate mitt to clean the lower parts.
NEVER clean the car when the paintwork is hot to the touch. You'll get away with cleaning it in the Autumn/Winter when the sun's out but never in direct sunlight during the summer. When the paint is hot it's softer and more easily scratched
When the who car has been cleaned, rinse thoroughly using moderate pressure to remove the shampoo then rinse using an open hose.
If the car is waxed the water will pretty much drag itself off the bodywork meaning you only have to blot up the remaining water with a microfibre drying towel.
Chamois leathers are a big no no as they are likely to cause scratches/swirls
