TRANSTAR® 4613 2‑in‑1 Primer is a ready‑to‑spray aerosol formulated for rapid sandable priming of a wide range of automotive substrates. It combines adhesion promotion and sanding finish in a single application, making it suitable for panel repair, filler bonding, and finish preparation in body shop environments.
The primer reaches flash time in 5–10 minutes and is sandable within 15–20 minutes, allowing fast turnaround on repair cycles. With a coverage rate of 432 ft² per gallon at a 1 mil film thickness, it provides efficient material usage across aluminum, e‑coat, fiberglass, galvanized steel, OEM finishes, plastics, SMC, and other common substrates. The product maintains a one‑year shelf life when stored properly.
Safety is governed by a Danger signal word. Use eye protection, chemical‑resistant gloves, protective clothing, and a respirator in a well‑ventilated area. The aerosol has a flash point of 104 °C (‑155 °F) and contains multiple GHS hazards, requiring standard PPE and adherence to SDS guidelines.
