Rust-Oleum Filler Primer is a hi-build formula that fills in minor imperfections in the surface and improves topcoat adhesion and appearance. Use on metal, wood and fiberglass surfaces. Do not use on surfaces that will come in direct contact with heat or high temperatures such as mufflers or exhaust components. Filler Primer is especially recommended for automotive refinishing to provide a uniform base to enhance the appearance of the topcoat finish.
NOTE: It is not allowed to send this item through air mode. Surface mode is enabled for the same. Thus, shipping will be done through surface.

How to Apply Filler Primer Paint?
Suitable Conditions to Use
Use outdoors or in a well ventilated area such as an open garage. Use when temperature is between 50-90°F (10- 32°C) and humidity is below 85% to ensure proper drying. Do not apply to surfaces that, when heated, exceed 200°F (93°C) or galvanized metal.
Make Your Surface Ideal
Clean the surface with a mild ammonia based cleaner and warm water. Rinse and then dry with a clean lint-free cloth. Wipe the entire area with Rust-Oleum Wax & Tar Remover and a clean lint-free cloth to remove any dirt, grease, wax or petroleum based material.Remove loose paint and rust with a wire brush or sandpaper. Scuff sand and feather edge the entire surface with #1000 grit sandpaper, Scotch Brite pad or equivalent. Repeat cleaning the surface with a mild ammonia based cleaner and warm water, rinse and dry the surface with a clean lint-free cloth. Use a tack cloth to remove any sanding dust or particles. Mask surrounding areas to protect from overspray.
Rust-Oleum Filler Primer is ready to use and does not require any reducing, but can be tinned with Rust-Oleum Acetone if desired. Mix thoroughly to ensure any settled pigment is re-dispersed. Strain Filler Primer with a fine screen before pouring it into a spray gun cup. Set the conventional spray gun pressure to 30-40 psi. Apply 2-3 coats allowing 5-10 minutes of dry time between coats. Do not use near open flame.
