When it comes to priming motorcycle plastics for restoration, it's important to choose a primer specifically designed for use on plastics. Traditional canned primers may not adhere well to plastic surfaces, leading to poor results.
One suitable option for priming motorcycle plastics is a plastic adhesion promoter or plastic primer. These products are specifically formulated to bond to plastic surfaces and provide a suitable base for paint application. They help improve adhesion and durability of the paint finish.
Before applying the plastic adhesion promoter or primer, it's crucial to thoroughly clean the plastic surfaces to remove any dirt, grease, or contaminants. Follow the manufacturer's instructions for proper surface preparation and application techniques.
Some well-known brands that offer plastic adhesion promoters and primers include Dupli-Color, SEM, and Krylon. You can find these products at automotive or motorcycle supply stores, as well as online retailers.
It's always a good idea to test the primer on a small, inconspicuous area of the plastic surface first to ensure compatibility and proper adhesion. This allows you to assess the results and make any necessary adjustments before proceeding with the full restoration.
Additionally, if you are unsure about the specific primer to use for your vintage Honda CT 90, it's recommended to consult with a professional motorcycle restorer or seek advice from experienced enthusiasts who have successfully restored similar motorcycles. They may have specific recommendations based on their own experiences and knowledge.
