Graco's stated niche application: curtainwall and glass installation (insulating glass sealing), handling silicones, urethanes and polysulfides. Quotable quality feature: automatic shutdown on off-ratio conditions to prevent seal failure on insulating glass — the failure being prevented is a fogged/failed IG unit in a building facade, a warranty event measured in years. Manuals 3A2894EN-V, 332452EN, 332453EN-G, 348833EN-E, 339934EN-C. Real asset gap: no product photo exists on this page (marketing/calculator page, no img tags).

Automatic shutdown on off-ratio conditions exists specifically to prevent seal failure on insulating glass — off-ratio two-component sealant is the failure mode this feature is built against, and the resulting fogged/failed IG unit surfaces as a warranty claim years after install, not on the line.
An off-ratio insulating-glass seal doesn't fail on the shop floor — it fails in the field, years later, as a fogged unit and a warranty claim against the building facade. AGP's automatic off-ratio shutdown exists specifically to catch that failure before the unit ships, which is the whole reason to spec a glazing-specific proportioner instead of a general meter-mix system on curtainwall work.
