Choosing the right automotive paint can make all the difference to the appearance, durability and ease of application of your project. Whether you’re restoring a classic car, repairing accident damage or repainting commercial equipment, understanding the different paint systems will help you achieve the best results.

Cellulose Paint

Cellulose paint has been used on vehicles for decades and remains a popular choice for classic car restorations.

Best suited for:

• Classic cars manufactured before the 1980s
• Vintage motorcycles
• Restoration projects where originality is important

Advantages:

• Fast drying
• Easy to apply and repair
• Can be polished to a high gloss
• Blends well when repairing small areas

Considerations:

• Less resistant to chemicals and weather than modern paints
• Requires regular polishing to maintain its finish
• Lower durability compared with newer paint systems

If you’re restoring a period vehicle and want an authentic finish, cellulose paint is often the preferred option.

2K Acrylic (Two-Pack) Paint

2K acrylic paint consists of paint mixed with a hardener, producing a tough, durable finish with excellent resistance to everyday wear.

Best suited for:

• Modern cars
• Commercial vehicles
• Plant and machinery
• High-end restorations
• Areas requiring maximum durability

Advantages:

• Exceptional gloss retention
• Highly resistant to fuel, chemicals and weather
• Excellent scratch resistance
• Long-lasting professional finish

Considerations:

• Requires accurate mixing with hardener
• Suitable spray equipment and appropriate respiratory protection are essential
• Primarily intended for professional use

For professional bodyshops and experienced refinishers, 2K acrylic remains one of the most durable paint systems available.

Solvent-Based Basecoat

Solvent-based basecoat provides the colour layer on many vehicle refinishing systems and must always be protected with a clear lacquer.

Best suited for:

• Modern solid colours
• Metallic finishes
• Pearlescent finishes
• Spot repairs and panel blending

Advantages:

• Excellent colour accuracy
• Quick drying
• Easy to blend into existing paint
• Large range of manufacturer colours

Considerations:

• Requires a compatible clearcoat
• Not designed as a standalone finish

This system is widely used for refinishing work where a high-quality factory-style finish is required.

Water-Based (Waterborne) Basecoat

Water-based paint has become the standard refinishing system used by most vehicle manufacturers and professional bodyshops. It uses water as the primary carrier instead of traditional solvents, making it more environmentally friendly while still delivering excellent colour matching.

Best suited for:

• Modern cars
• Manufacturer-approved repairs
• Insurance repair work
• Metallic and pearlescent finishes

Advantages:

• Outstanding colour matching
• Lower VOC (volatile organic compound) emissions
• Environmentally friendly
• Excellent coverage and blending
• OEM-approved by many vehicle manufacturers

Considerations:

• Requires a compatible clearcoat for protection and gloss
• Drying may require airflow or specialised drying equipment
• Best applied in controlled workshop conditions

Water-based basecoat has become the preferred choice for most professional bodyshops, offering excellent results while meeting modern environmental regulations.

Synthetic Paint

Synthetic enamel paint is a durable, economical coating widely used outside conventional passenger vehicle refinishing.

Best suited for:

• Agricultural machinery
• Trailers
• Commercial vehicles
• Plant equipment
• Chassis and components

Advantages:

• Cost-effective
• Good weather resistance
• Tough finish
• Wide colour range
• Simple application

Considerations:

• Longer drying time

• Not normally used for high-end automotive refinishing

Synthetic paint remains an excellent choice where durability, ease of maintenance and value are the priorities.
