Masking systems from 3M can be used in all coating and repair processes, ranging from standard masking tape to special applications and solutions.
Worldwide, 3M is one of the largest and most experienced manufacturers of adhesive tapes. For car refinish tasks, masking tapes play an important role in all core processes. Intensive research and development work within 3M constantly assures additions of innovative products to make customer processes more secure.
Such innovative examples are the advanced aperture masking tape Soft Edge Foam Masking Tape Plus and Scotch® Transition Tape. The novel design of these two products allows significantly softer paint edges and transitions, greatly reducing rework. Just two of many products from 3M that actually improve the body shop work process.
Prior to any car repair or any painting, parts of the car which are not to be worked on, need to be protected from unwanted damage, soiling or paint overspray.
Working thoroughly from the very beginning reduces or even eliminates any clean-up or rectification afterwards.
Time consuming masking activities can be minimised by using high quality material and good application techniques and it is always worth investing into premium masking tapes, which can be effortlessly removed without slithering, slicing or leaving adhesive residue.
In general, the following materials should be used and ready at hand:
For the fastest, reliable aperture masking, use 3M Soft Edge Foam Masking Tape Plus, which is ideal for moveable car parts such as doors, bonnet or booth lids, and designed for the modern narrower appertures. Apply the tape along the car body line WITHOUT stretching and press lightly in both directions. One size fits all openings.
For masking special parts such as door handles, detailing applications, bumpers or plastic parts, use special products such as fine line tapes like Scotch® Fine Line Tape 471, which allow precisely following contours and edges and have a very high flexibility. Using special products for special applications saves time, material and rectification work!
Cover the whole car except the repair area by using a 3M Masking film of your choice.
Using 3M Masking film reduces work time as it allows you to cover the car fast with one person only. The Film will cling to the car, prevent the surface from any unwanted overspray and provides you with visual control as it's transparent.
Prepare the larger area that you need to respray including application of aperture masking solutions such as 3M Soft Edge Foam Masking Tape / Soft Edge Foam Masking Tape Plus and / or 3M Scotch® Transition Tape, which are applied to the car body line of any moveable parts to close gaps.
If you need to work around rubber parts, 3M Trim Masking Tape protects these and hold them back and allows the paint film to go underneath the rubber seals and leaves the parts with a very clean rim.
Cut the masking film around the repair area and fix the film with 3M Masking Tapes, in preparation for filler and primer application.
For best results, apply Scotch® Transition Tape on top of the 3M Masking tape to allow a smooth transition of primer edges.
Before applying the base and clear coat, further cut the masking film and attach it to contour and aperture masking.
