Best Masking Tape for Curved Lines: What to Use

Automotive paint allows car owners to customize their vehicles and create a completely unique look to suit them. This can often include painting curved lines, whether this is for a design or a few curved pinstriping lines. So as automotive professionals, how can you make sure you’re achieving the best possible finish on these types of paint jobs? JTAPE has designed tapes to be used for all kinds of customization jobs, including painting the perfect curved lines with defined edges. Here are a few tricks to help you out.

How to Create Perfect Curved Lines for Automotive Painting

Wondering which masking tape is best suited for creating the perfect curved lines your customers are looking for? Look no further. Below, we’ll explain JTAPE’s top two tapes for customizing and take you through some of their best properties.

Customizing Tape

Fine Line Masking Tape

JTAPE’s range of fine line tapes includes purple, blue, green and orange. While each of these has its own distinct properties, they’re all excellent for masking curved lines onto the bodywork of a vehicle. Like JTAPE’s customizing tape, they also won’t leave any residue on the surface when removed, meaning you’ll be left with clean curved lines finished to a professional standard.

Using Fine Line Masking Tape for Masking Curved Lines

Purchased JTAPE’s fine line tape and ready to start painting curved lines? Here, we’ll explain how to use JTAPE’s high-quality range of fine line masking tapes to create crisp defined lines that leave no adhesive residue behind.

The process is simple. All you need to do is apply the tape to a clean surface on the car and curve it to the desired shape. The flexibility of the tape makes this process quick and easy since it’ll conform in any way you want it to. Whether you’re looking for a slight bend or harsh curves, JTAPE’s fine line tape can do it all.

First, mark out where you want the curve to be and ensure you have a rough idea of where it should start and end. You can then start to play around with your fine line masking tape to find the ideal placement. Since the tape won’t leave any residue, it’s easy to place and re-place it as needed.

It can often take a few attempts before you settle on the placement for a curved line that matches the existing bodywork and lines on the vehicle. It’s best to work with the existing lines if the customer doesn’t want anything too drastic as these will help your thin lines look more uniform. For a more unique look, it might be worth straying away from the existing curves and lines to help your new pinstriping or customization work stand out.

Customizing tape, as we’ve mentioned, is also a great option for masking curved lines. The main difference between this tape and our fine line tape application is that this can be torn into smaller stripes. This allows you to create curved, clean lines adjacent to one another, as is necessary for pinstriping applications. The flexibility of the tape also allows for masking tight contours and the creation of any creative curves, making it the perfect solution for customised car bodywork, motorbikes and helmets.

Before spray painting, you’ll need to decide how many lines you want and where you want these to be. For example, you could place the tape on a curve and pull two stripes away to create two thin painted lines.

To achieve the best finish, you might require additional masking tapes or films to protect the surrounding surfaces from overspray. This will ensure the spray paint is only applied to the curved lines you’re trying to create, which will help keep these crisp and sharp. Using JTAPE products and these top tips, you should be masking curved lines onto any vehicle to the professional standard you and your clients want.
