In the world of automotive painting, there are two main methods for masking off areas that don't need to be painted: tube tape and back tape. Both methods have their own advantages and disadvantages, and the best choice for a particular job will depend on the specific situation.

Tube Tape

Tube tape is a pre-formed, round tape that is applied to contours and gaps. It is easy to apply and can be repositioned in seconds. Tube tape also flexes to fit sharp corners and feathers naturally for touch-up painting.

Advantages of Tube Tape:

·         Takes half the time of back taping

·         Proper installation requires little training

·         Round shape to fit contours, fill gaps

·         Goes on in 1 step

·         Repositions in seconds

·         Flexes to fit contours, even sharp corners

·         Round shape naturally feathers edges for touch-up painting

Disadvantages of Tube Tape:

·         Can be more expensive than back tape

·         Not as strong as back tape

Back Tape

Back tape is a flat, roll-on tape that is applied to flat surfaces. It is strong and durable, but it can be more difficult to apply and may require shaping and folding to fit curves.

Advantages of Back Tape:

·         Strong and durable

·         Less expensive than tube tape

·         Can be used on flat surfaces

Disadvantages of Back Tape:

·         Takes 2X longer than tube tape to apply

·         Proper installation requires experienced painter or prep man

·         Flat shape can leave hard edges

·         Goes on in 3 steps per gap

·         Often needs redoing

Which Method is Right for You?

The best method for masking off areas that don't need to be painted will depend on the specific situation. If you are masking off a large area with many contours, tube tape is a good choice. If you are masking off a small area with flat surfaces, back tape is a good choice.
