I was tempted. A friend wanted me to “change the surface color” of one section of exterior siding bordering a new wood deck and spa. No thanks! The siding was under a 15-year warranty.
Another friend wanted me to paint over the clear glass on each of his security system units.I thought about, even experimented by, custom mixing, then painting on a similar piece of glass.
Final advice: I wouldn’t advise it. The security system and units were under warranty.
Cardinal rule: Never paint the surface of any pre-finished product under warranty.
Examples: Exterior siding, security lighting systems, woods, metals, certain roofing, appliances.
- Always apply coatings or finishes according to manufacturer’s recommendations.
- Always provide the proper surface preparation.
- Do not apply a finish on an unstable surface. Examples: Hot, cold, too rough.
- Do not apply finishes over incompatible coatings. Result: Early paint failures.
- Make sure the primer and finish combinations are compatible.
- Do not use paint to alter a product, which at some time you may need or want to return.
Coating warranty-covered surfaces and products calls for special vigilance, and a keen eye.
