Tackle your next repair with the confidence of a seasoned pro by reaching for a six-ounce SemKit of PPG® P/S 870 B-1/2 Gray Sealant. This corrosion-inhibitive sealant is tailor-made for aircraft maintenance, especially when long-lasting protection is essential. It meets BMS 5-95 Type I Class B-1/2 specifications, meaning it’s not only trustworthy, it’s already proven to work under pressure. With a working time of about 30 minutes and a cure time of around six hours, it strikes that sweet spot between cures too-fast and please-hurry-up. Use it for fillet sealing, fay surface sealing or other critical sealing tasks where durability matters.

The real magic? This stuff sticks. PPG® P/S 870 bonds readily to aluminum, titanium, steel and even top-coated surfaces, forming a tough, flexible rubber seal that’s as weather-resistant as it is strong. And since it’s gray, it blends in nicely with most surfaces for a professional finish. Ideal for use in pressurized cabins and other aircraft zones where reliability can’t be compromised, this sealant is trusted in hangars worldwide. So if you’re tired of fixes that won’t stick and sealants with questionable cure rates, let PPG® P/S 870 B-1/2 Gray Sealant from SkyGeek take a turn handling the job.
