Abstract
A reusable magnetic masking member for keeping a surface area of a metal object from being painted during a painting operation. The magnetic masking member includes a flexible magnetic sheet of material which is magnetically attached to the surface area of the metal object and includes an exterior vinyl film backing which may be cleaned of excessive paint after a number of reuses and repeated paintings.
Claims17
A method of preventing wicking of paint while protecting a machined brake shoe receiving surface of a brake head from being painted, comprising the steps of:
- (a) selectinq a flexible sheet of magnetic material having a magnetic attraction at least sufficient to prevent wicking of paint,
- (b) cutting a reusable magnetic masking member from said flexible sheet to conform to the machined brake shoe receiving surface,
- (c) placing said cut reusable magnetic masking member against the machined brake shoe receiving surface so it is magnetically attracted thereto,
- (d) painting the brake head including said cut reusable magnetic masking member,
- (e) removing said cut reusable magnetic masking member from the machined brake shoe receiving surface of the brake head so that steps (c), (d), and (e) may be repeated.
A method of preventing wicking of paint while protecting a given area of a magnetic object from being painted during a painting operation, comprising the steps of:
- (a) covering the given area of the magnetic object with a magnetic masking member which is magnetically attracted to the given area of the magnetic object with sufficient force to prevent wicking of paint;
- (b) painting the magnetic object as well as the magnetic masking member;
- (c) permitting the paint to dry;
- (d) removing the magnetic masking member from the given area of the magnetic object so that steps (a), (b), and (c) may be repeated.
A method of preventing wicking of paint while preventing a brake shoe receiving surface of a disc brake head assembly of a railway vehicle from being painted during the painting operation, comprising the steps of:
- (a) pre-cutting a reusable magnetic masking template member to conform to and cover the brake shoe receiving surface of said disc brake head assembly, said reusable magnetic masking template member having sufficient magnetic attraction to prevent wicking of paint.
- (b) placing said pre-cut reusable magnetic masking template member against the brake shoe receiving surface so said pre-cut reusable magnetic masking template member is magnetically attracted thereto,
- (c) painting the brake head assembly including said pre-cut reusable magnetic masking template member,
- (d) removing said pre-cut reusable magnetic masking template member from the brake shoe receiving surface of the brake head so that steps (b), (c), and (d) may be repeated on another brake shoe receiving surface of a disc brake head assembly.
