What’s the best paint for your classic car?

Choosing the perfect paint job for your classic car isn’t just about picking a colour that turns heads; it’s about marrying aesthetics with performance and ensuring your ride stands out, not just at the next car meet but also in durability and maintenance. When it comes to giving your automotive treasure a facelift, the palette you pick plays a pivotal role in its curb appeal and how it battles the elements and time itself.

Let’s dive under the hood of this topic and explore the ins and outs of automotive paints, shall we? From the glossy allure of urethane paints that promise longevity and a show-stopping shine to the eco-friendly charm of water-based paints that are kind to Mother Nature and your health (because the only thing we want to take our breath away should be the car’s beauty, not the fumes), there’s a spectrum of choices for every type of car enthusiast. Whether you’re a weekend warrior with a garage project or a professional detailer aiming for that concours-level finish, understanding the characteristics of each paint type—such as their visual impact, cure times, and resilience against wear and tear—can make or break the outcome. And remember, the best paint job is not just about what’s on the surface; it’s also about what’s underneath. So, before you commit to a colour, make sure your classic’s body is as smooth as a billiard ball (unless you’re going for that “driven through a sandstorm” aesthetic).

Solvent-based or solvent-free paint for your classic car?

When picking the perfect paint for your classic car, it often boils down to solvent-based versus waterborne acrylics. This decision isn’t just about splashing colour on metal; it’s about finding the perfect blend of durability, aesthetics, and environmental responsibility for your cherished ride. Think of it as choosing between a timeless vinyl record and a crisp digital download—each has charm and advantages.

Solvent-based paints have been the classic choice for decades, offering that deep, lustrous finish that makes your classic car look speedy even when parked. They’re the heavy hitters in terms of durability and resistance to the elements, ensuring your car looks stunning on the day of the paint job and continues to turn heads for years to come. Then there’s the waterborne acrylic paint, the eco-friendly contender gaining traction in the automotive world. These paints are not only easier on the planet but also boast quicker drying times and reduced emissions, making them a favourite among DIY enthusiasts and professionals aiming for a healthier work environment (and let’s be honest, the only thing we want to be toxic is the rivalry at car meets, not our paint).

Choosing between solvent-based and waterborne acrylic paints ultimately depends on your priorities: the unmatched depth and endurance of solvent-based paints or the environmental benefits and ease of use provided by waterborne acrylics. Regardless of your choice, meticulous preparation and application are the keys to a jaw-dropping finish. Remember, a paint job is only as good as the effort and care. So, take your time, choose wisely, and prepare to give your classic car a finish as impressive as its heritage.

Solvent-based body paints

Solvent-based body paints are the secret sauce for achieving that deep, luscious look on classic cars, offering an unmatched ability to blend tints and resins into a smooth, flowing canvas. These paints are the muscle cars of the paint world—powerful, bold, and with a finish that screams, “Look at me!” The magic lies in the solvents, which act like a skilled bartender, mixing the resin and pigments to the right consistency. As these solvents evaporate during drying, they leave behind a rich colour and durable surface ready to face the sun, wind, and admiring glances. The cocktail of active compounds, including xylene, toluene, and ethyl acetate, ensures your classic ride isn’t just painted; it’s enveloped in a coat ready to roll out and turn heads.

However, as with anything that packs a punch, there’s a flip side. The toxicity of solvent-based paints is a known pitfall, posing risks not only to the health of those applying it but also to the environment, contributing to the greenhouse effect (like that car that looks great but has a questionable emissions test). This has led to stringent regulations around their use, necessitating a garage dress code of overalls, a type A cartridge respirator, protective goggles (because safety shouldn’t be optional, like that optional extra you wish you’d added to your car), gloves, and a workspace that’s more ventilated than a convertible on a summer day. Regarding maintenance, think of your health as you do your car’s maintenance: replace the mask cartridge at the first whiff of trouble, and clean your hands with 95° alcohol—not with thinner, unless you’re aiming for a DIY chemical peel. Solvent-based paints require careful storage, away from the living quarters, kids, and pets, treating them with respect due to their power and potential, much like handling a vintage engine with care and a sense of awe.

Acrylic waterborne body paints

Acrylic waterborne body paints are cruising onto the scene as the eco-friendly alternative to traditional solvent-based options, steering the automotive paint industry toward a greener horizon. Think of them as the hybrid cars of the paint world: less pollution, more innovation. Swapping chemical solvents for water, these paints are easier on the lungs and the environment and align with the European Directive 2004/42/EC’s mission to put the brakes on Volatile Organic Compounds (VOCs). With VOC levels now throttled down to a mere 2% (below 20 g/L), compared to the gas-guzzling 35-70% of their solvent-based counterparts, the air in your garage is about to get much fresher. Plus, cleanup is a breeze—just water needed—making post-paint job rituals less of a toxic event and more of a simple rinse and repeat. And let’s not forget, with water as the diluent, you’re not just painting; you’re giving your car a drink (and who said cars don’t get thirsty?).

However, acrylic waterborne paints haven’t always been in the fast lane. Initially, they were like the underdog in a drag race—criticized for their longer drying times and questioned for their strength and sleekness. But hold onto your steering wheels because, with new water-based acrylic polyurethane resins, these paints are now shifting gears, offering finishes that can rival or even outshine their solvent-based rivals in vibrancy and durability. Sure, they might still lag a bit in the longevity department, but they make up for their lack of endurance in environmental and health benefits. It’s a trade-off, like choosing between a classic muscle car that’s a bit of a gas hog and a modern electric vehicle that’s light on emissions but heavy on tech. In the world of car paints, acrylic waterborne options are proving that sometimes, the best way to move forward is with a bit of water power.
