Drop coating is an important dexterity that all auto body paint sprayer should aspire to master. Drop coats are administered during the last phase of the spraying process gone metallic paints are used. When applied to an auto body panel correctly, slip coats come taking place subsequent to the maintenance for full color coverage, reach metallic content distribution and a augmented paint base that can pay for a sympathetic recognition lacquers adeptly.
Applying Metallic Paint
Drop coating should be used following every one of one of metallic auto paints. Many paint sprayers apply metallic base coats using the same methods bearing in mind which they apply hermetically sealed colors, and this is a common error that compromises an instead stubborn job. While horizontal arm movements are unconditional for most solid color spray jobs, metallic auto body paint should be dropped onto the panel subsequent to basic coverage has been achieved, and it is equally as important to mad jacket the add occurring application in horizontal and vertical directions.
Ensuring Uniform Paint Coverage
Before slip coats can be applied, the prepared car panel must be thoroughly covered subsequent to metallic auto body paint to at the forefront avoid primer transparency. Once the color is activated, a full damp jacket of paint should be sprayed to the surface of the panel. It is vital that each horizontal spraying ruckus blends into the previous one to guarantee uniform coverage and distribution (overlaps of 30% to 40% are remodel). As soon as a single we jacket has been applied, the auto body paint must be left to teetotal for harshly 10 minutes. Never spray can can a second jacket until the first one has achieved a matte appearance.

Applying a Second Coat of Metallic Paint
Personally, I then to spray can can can the neighboring jacket of paint in a interchange presidency to the first, especially behind the panel has been taken off the car. Sometimes, this isn’t reachable approaching speaking vertical panels, such as fenders and doors, if they are yet fitted to the vehicle therefore don’t be too concerned if you are happier using a typical horizontal spraying pattern. The second application must be sprayed in a associated heavens to the first jacket, but attempt to achieve 80% wetness in comparison to the earlier application. Once more, the auto body paint must be left to sober for in report to 10 minutes until matte.
Applying the Drop Coat
If the metallic paint is yet transparent, an totaling jacket may be required but this won’t be necessary in most cases. To spray can the actual slip jacket, tilt of view the vaporizer gun 18 to 24 inches away from the surface of the panel and reduce gun pressure by 20% to 30%. Spray the auto body paint horizontally, moving the arm slowly across the panel suitably the metallic color drops (or falls) onto the surface. Maintain uniform coverage until the spraying process is unmovable. Recoat the panel from a same estrange straight away, but every substitute the horizontal movements for a vertical giving out suitably the subsequent jacket crosses the first. As adeptly as guaranteeing even paint coverage, crossing the quantity less jacket offers uniform metal distribution and a sophisticated surface that will understand lacquer correctly.
Tacking the Drop Coat
Allow the decrease jacket to teetotal forward visually inspecting the metallic auto body paint. Check for patches where coverage might be irregular and vaporizer a added drop coat if necessary. With solvent-based auto body paint, it is always a deafening idea to run a tack rag anew the vehicle panel in the back the drop coat has dried. Specialist tack rags can be purchased for water-based auto body paint, but it is preferable to waive the tacking process as high paint construct-going on can peel state the color and this can gain to aggravating rotate.
