Make Your Car Great Again: The Silent Killers of Car Paint

The Hidden Dangers Lurking in Singapore

In Summary (TLDR):

• Singapore's rising UV index and acidic rainwater are the top causes of paint fading and corrosion.

• Bird droppings are highly acidic — clean them quickly before sun exposure bakes them into the paint permanently.

• Road debris and flying stones cause chips; keep distance from vehicles ahead and consider Paint Protection Film.

• Carpark door dings are common — choose corner lots and avoid parking beside vans or delivery trucks.

• Apply liquid wax every 2–4 weeks for basic paint protection; ceramic coating (like 9H Tonyin) lasts up to 2 years and offers superior UV and scratch resistance.

• Polish every 6–12 months to restore gloss and remove stubborn stains.

• Prevention is the cheapest cure — shade, smart parking, and safe driving habits go a long way.

  
  

The Weather Woes of Singapore

Singapore's weather can be quite erratic. One moment the sun is blazing hot, and the next, a sudden downpour occurs in the blink of an eye. The rain and shine are your car's greatest enemies, no mistake about that.

Let's start with the sun. The UV index measures how strong the level of solar radiation is on the Earth's surface. Singapore's average UV index has been gradually increasing from 2.6 in 2023 to close to 3.0 today, with its maximum UV index hitting 11.0 very frequently over the past year. It is not only bad for your skin but also harmful to your car's paint. These harmful UV rays from the sun can break down the pigment in paints, leaving the paint faded or discolored.

The Perils of Rain

A good car wash from rain, you'd say? Rain in Singapore is not a good thing either. Studies have shown that rainwater in Singapore has hit an acidic pH of 4.2 - 4.6 (neutral pH 7.0). This acidity, attributed to transportation, refineries, and industrial pollution, accelerates corrosion and damages paint. This is one of the reasons why rain leaves marks on your car body when rainwater does not run away naturally.

Most of the time, a good polish can lighten or remove these water stains, but sun-kissed paint will require a respray of fresh paint.

The Bird Dropping Dilemma

Singapore is home to 390 bird species and a thriving crow population. Many open car parks have trees to beautify the area, but they also bring a pain to car owners — bird droppings! These feathered freeloaders soar through the skies with one mission: to relieve themselves at maximum inconvenience. Somehow, your freshly washed car always becomes ground zero. If not cleaned in time, plus some baking under the sun, the acidic droppings may damage the paint and leave a lasting mark to remember.

Polishing will not be able to fully remove such marks if they have penetrated deep into the top coat.

Road Debris: The Hidden Threat

Our roads are constantly littered with small stones ready to pick a fight with your car. This is worse on roads that have ongoing construction. So drive slow and do not tailgate the car in front. Your best defense against wild projectiles is to keep your distance and slow down. Otherwise, applying a Paint Protection Film over the car should do the trick as well.

Carpark Conundrums

Our car parks may seem innocent, but they are where the majority of the bruises come from. Not sure if it is the small car park lots or the gigantic size of Singaporeans who love to do a full swing of their doors, but our cars feel the impact of their "neighbourliness." We usually recommend our friends avoid parking in small lots, beside delivery vehicles, and choose corner parking lots where possible.

Every day. Rain. Sun. Birds. Rocks. People.

Your car doesn’t complain. It doesn’t fight back. It just… takes it all.

Fret not. We at Ngai Hong Spray Painting have several solutions to combat these battles and come out triumphant!

Solutions to Protect Your Car

1. Create a Cleaning Schedule for Your Car. Over time, dirt, dust, and debris build up on your car and require a good wash. For cars with dust all over, we can skip the shampoo and use a clean, wet cloth to go through. After a good wash, your job is not done yet. Apply off-the-shelf liquid wax every 2 weeks to a month! This step will help you on your future washes and provide a layer of protection over your car from UV and acidic droppings.

   
   

2. Regular Polishing and Coating. Polishing helps with removing stubborn stains and dirt, as well as restoring the gloss of the paint. This can be done every 6-12 months. Professional coatings are chemicals that last much longer than wax and offer more protection against external factors. For instance, ceramic coatings usually have a hardness rating that indicates scratch resistance. The higher the number, the more resistance it has against scratches.

   
   

   Check out our 9H Tonyin Ceramic Coating. Renowned for its water-beading surface coating, dust and water do not stick onto the paint surface, providing ease of cleaning. Its UV resistant properties enable your paint to look bright and great for years to come! We recommend applying it once every 2 years.

   
   

3. Avoid the Source of Destruction. Prevention is better than cure. We recommend avoiding long exposure to the sun and rain (where possible) and parking in areas that are not directly under trees, as it may risk bird droppings or tree sap stains. Find car park lots that have wider spaces to reduce the risk of door opening dinks by others; try to avoid parking beside vans and delivery trucks where possible. On the road, always be on the lookout for road debris that may risk flying onto your car or damaging your undercarriage. Protecting your car paint begins with correct knowledge and a conscious effort.
