Allow more time at cooler temperatures. Dries to touch in 10 minutes and dries to handle in minutes.

A topcoat must be applied within 10 minutes after primer application. For best results apply a finish coat of Rust-Oleum Automotive finish. Using a scuff pad or sand paper before painting or priming plastic is a good idea. Our favorite adhesion promoter for plastic and metal is Bulldog Adhesion Promoter. Light to Medium Coats- When applying clear coat to plastic make sure they your first coats are light or medium and not applied too heavily.

Both primers and adhesion promoters are strongly adsorbed onto the surface of the substrate. The adsorption may be so strong that instead of merely being physical adsorption, it has the nature of a chemical bond. The main difference between primers and adhesion promoters is that primers are liquids.

To spray, hold can parallel inches from the surface to be coated and use in an even, sweeping motion. To avoid runs and sags, apply in light coats. Allow primer to dry for minutes between coats. Apply color coat within last 10 minutes of primer coat. This primer system is somewhat universal in nature and also works on a variety of paint and bare metal surfaces.

Adhesion promoter improves adhesion for all paints and acts like a clear primer. Ideal for interior or exterior surfaces, like plastic, chrome, fiberglass bumpers and aluminum trim molding. Comes in an easy to use 11 ounce aerosol can. After the final sanding, wipe the headlight clean using a clean towel. Make sure to remove all traces of grit on the lens before applying the clear coat.

There are several brands and varieties of clear coat on the market today and one of those varieties is a spray. Go lighter on the surrounding clear coat, as you are trying to smooth and blend the damaged area, not remove more clear coat.

Solvent test: Apply a quality lacquer thinner or basecoat reducer on a rag to soak a spot on the bumper cover. Allow the surface to stay wet for at least 5 minutes. If the primer lifts, remove all affected areas.

Advertisement Tape test: Taking a piece of 2-inch masking tape, firmly press a strip onto the bumper cover surface about six to eight inches long. Pull the tape off quickly. If the coating comes off, the entire part must be stripped. If the primer starts to lift or peel, completely remove all the affected primer. All affected primer must be removed to ensure there is no lifting during the paint process.

Treat the part as a bare plastic repair. Use caution while stripping primer with solvents. You may need to periodically wipe the surface with isopropyl alcohol or a damp rag with water to avoid static buildup. Clean the part completely. After stripping the bumper cover, wash completely with a good cleaning solution soap and warm water to remove water-soluble contaminants. Be sure to rinse thoroughly and dry the part off before continuing.

Be sure to clean and scuff corners and crevices well for maximum adhesion. Rinse and dry thoroughly. Advertisement 2. Use a plastic cleaner designed specifically for pre-cleaning plastics. Traditional solvent cleaners may not clean the surface properly and may actually re-contaminate the surface by soaking into some plastics, later releasing the solvent cleaner or mold release agents that float to the surface causing delamination of paint.

Advertisement 3. Be sure the entire bumper cover has been cleaned and abraded. Re-clean the surface with plastic cleaner to remove residue. In most cases, a plastic adhesion promoter must be applied over bare plastic areas before priming or sealing. Advertisement Replacement Unprimed. Pre-baking or tempering plastic: If a bumper cover will be baked after the topcoat has been applied, we recommend pre-baking the part to help remove additional release agents and contaminants prior to refinishing.

After pre-baking the bumper cover, allow to cool and proceed with the cleaning and preparation process. Pre-baking a bumper cover can be done in a booth while another vehicle is going through a bake cycle, or positioning a heat lamp 3 to 4 feet away and warming the plastic for 15 to 30 minutes per exposed area. Do not over-heat bumper covers. After pre-baking, continue with the repair and refinish process.

Advertisement 1. The use of a gray scuff pad will help to break up contaminants and start to abrade the surface at the same time. Rinse thoroughly and dry the part off before continuing. In addition, a scuffing agent should be used during the washing step. Use a gray scuff pad to apply the scuff agent. Advertisement After a thorough cleaning, allow the plastic part to flash off for 15 to 30 minutes to release solvent and then continue with the repair.

Be sure the entire bumper cover has been completely abraded. This can be done during the original cleaning process with a scuff pad and scuffing agent to save time. In most cases, a plastic adhesion promoter must be applied over bare plastic areas before priming, sealing or topcoating. Apply 1 to 2 coats of adhesion promoter, allowing for a 2- to 5-minute flash between coats. Allow a 5-minute flash before applying primer, sealer or topcoat. Advertisement 4. Additional primer or sealer may not be necessary.

Excessive coats of primer, sealer, color or clear will reduce flexibility and may cause premature paint failure. Advertisement Rinse thoroughly and dry the part off before continuing. Use a mild solvent cleaner designed specifically for final cleaning before topcoating. Traditional solvent cleaners may not clean the plastic properly and may actually re-contaminate the surface by soaking into some plastics, later releasing the solvent cleaner or oils that float to the surface causing delamination of paint.

Be sure to wipe off the solvent cleaner while it is still wet on the surface. Make any necessary repairs. Some plastics require a pre-treatment prior to applying plastic repair materials or fillers.

Do not break through the existing color. Re-clean the surface with mild solvent cleaner to remove residue. Generally, the entire bumper will need to be topcoated due to the difficulty of melting in blend edges.

Washing with very warm to hot water and a good detergent is the first and most important step that many shops sidestep or avoid. A simple analogy is this: Advertisement Why do we wash dishes in hot water vs.

Hot water cleans better! Next, properly and completely abrading the raw plastic or the pre-primed part is necessary. Sand all areas, including crevices and corners. Follow this by properly applying plastic primer if and when needed. Do not over wet and puddle the primer. Allow it to dry properly before topcoating. Using a sealer and catalyzing the basecoat improves intercoat adhesion greatly. All repairs of parts including new unprimed replacement parts; new pre-primed parts; existing parts requiring minor repairs; and those which require repairs of heavy damage will begin with a wash with warm soapy water.

The unprimed part is cleaned with SCAT 2. Advertisement New Unprimed Replacement. Cleaned with SCAT 2 and a gray scuff pad or with the use of an alcohol-based cleaner.

After the part is thoroughly cleaned, abrade it with the B Scuff and Prep Paste using a gray scuff pad. Then, clean it again with Aqua SCAT 2, a gray scuff pad or with an alcohol based cleaner with a clean lint-free cloth. Advertisement New Pre-Primed. Then apply the topcoat of choice. Advertisement Block sand with grit and finish sand using or finer. After cleaning, apply sealer Kwik Seal, Kwik Prime, Hydrobase or epoxy primer and topcoat with your choice of colors.

If necessary, apply Rigid Plastic Repair to the back side of the panel to reinforce the repair. Once cured, sand it with grit and finish sand with grit. When dry, block sand with , then finish with or finer grit.

Bexloy and Lomod. Bexloy and Lomod are proprietary materials used by the carmakers. Advertisement Next, clean the part with Aqua SCAT 2 or an alcohol-based cleaner and dry it with a clean, lint-free cloth.
