Top Coats: When & How to Apply a Second Coat of HotShot
Typically, one coat of powder is all that is needed. However, some finishes such as Argent Silver, Reflective Chrome and New Smoke Chrome need to be top-coated with a clear or translucent finish to protect the shine.
1. Thoroughly cure the first coat at 400°F for 15-20 minutes after flowout. (Flowout is when the powder turns from its dry state to a liquid, wet-looking state.) Note: Cure the Reflective Chrome powder for 20 minutes at 375°F after flowout to assure a complete cure and shiniest finish.
2. Once the timed cure is complete, turn off the oven, open the door, and allow the part to cool without disturbing it.
3. Once cool, remove the part from the oven and support it as you did for the first coat.
4. Load the gun about one-third full with the appropriate color or clear powder. Note: Our Performance Deflector greatly increases transfer efficiency and helps in applying the second coat.
5. Attach the ground clip directly to a bare metal area on the part. You can do this by threading an old bolt into an existing hole, or simply scraping the powder from an inconspicuous area, and attaching the clip.
6. Apply the second coat in the same manner as the first, concentrating on the deep recessed areas first. After the part is thoroughly covered, disconnect the ground clip and give a light coating to the bare metal area. Cure as usual.
