A swab device for testing characteristics of a painted surface, comprising a packet having first and second sections, each of said first and second sections having inner and outer surfaces, said first and second sections being closed relative to each other in a pre-use condition so that said inner surfaces are in a respective opposing relationship, a first test pad mounted to said inner surface of one of said first and second sections of said packet, a first chemical testing substance effective for a testing characteristic of a painted surface being impregnated within said first test pad, and adhesive means on said inner surface of one of said first and second sections for securing said first and second sections substantially in said opposing relationship with said first test pad being contained therebetween after said first and second sections have been opened relative to one another and said first test pad has been used on a painted surface.
A method of testing paint on a surface comprising the steps of:
- providing a packet having a test pad sealed in air-tight relationship therein, said test pad being impregnated with a chemical testing substance effective for testing a characteristic of a painted surface, opening said packet to expose said test pad, adhering said test pad to a painted surface and allowing said test pad to remain in contact with the painted surface for a predetermined time, and removing the test pad from the painted surface and visually inspecting either the test pad or painted surface for a change of coloration indicating a characteristic of the painted surface.
