paint defects explained
Swirls are fine scratches that you see when the sun or bright light is on the paint and look almost like cobwebs, particularly as they appear to be circular. In truth, they aren't circular, swirls are lots of individual scratches which appear circular because of the way the light shows them. Swirls are most often caused by dirt and fine grit being rubbed across the paint during washing or drying.
An easy way to spot this kind of scratch is to run your fingernail across it. If you can feel it with your nail, then it is through the clear coat and can't be polished out. To completely remove this kind of scratch, the area will need painting - though these scratches can often be reduced with machine polishing even if they can't be removed completely.
Water spots form when the liquid from a droplet of water evaporates. When this happens, particularly if on a sunny day, the minerals in the water droplet remain behind, leaving a lasting spot on the paint. Sometimes, these spots can bake onto the paint and caneven etch into the clear coat.
Many things can make paint go dull, it can happen from chemicals affecting the paint, UV rays, scuffs, a build up of swirls or heavy concentration of scratches. Whatever the cause, dull paint can make your cars paint look really tired.
Bird poo etching
Bird poo can be very caustic. When it lands on your car, it has the possibility to etch into the clear coat and corrupt the paint, leaving a nasty stain behind. depending on the length of time it has been on the paint will determine whether it can be completely removed.
Holograms and buffer trails
When a car gets polished with a rotary machine polisher or too harsh a compound, holograms can get caused if either the user is inexperienced or if they don't finish down correctly. Either way, holograms usually look like curving or looping lines and look terrible. Rotary polishers, when used correctly are excellent tools which can deliver exceptional results, but in untrained hands can cause damage.
