An aircraft part comprising:

• an aluminum or aluminum alloy first piece, the first piece having a first piece surface;
• wherein the first piece surface has a clear, elastomeric sealant coating, the sealant coating formed from a two component, room temperature, cured, fast drying, sulfur free, polyurea/polyurethane/hybrid mix.

An aircraft part for use on the interior of an aircraft, the aircraft part comprising:

• a first piece and a second piece, each piece having a piece surface;
• wherein at least one piece surface has a clear, elastomeric, VOC-free sealant coating, the sealant coating formed from one of a two component polyurea/polyurethane/hybrid mix, with a fast hard dry time of less than about 30 minutes, the sealant coating with a peel strength between about 5 and 30 piw and a cured hardness of between about 20-80 Shore “A” at 77° F., and a thickness of between about 3 to 30 mil.

A two component cartridge for engaging a pneumatic mix and coat spray gun for use with assembly and maintenance of aircraft, the two component cartridge comprising:

• a body comprising a first compartment having a first mix part, a second compartment having a second mix part, wherein the first and second mix parts combine in the mixing straw to form a polyurea/polyurethane/hybrid fast drying VOC and sulfur-free mix that cures to form a clear, elastomeric, sealant coating;
• and
• a mixing straw, engaging the two compartments and disengageable from the body and having multiple dividers for mixing the two components and emitting, under pressure, the mixed components from a tip thereof.
