Just wondering if your product can be applied on vehicles that have been previously undercoated with lanolin based products, such as Fluid Film, Protection First Class, or Wool Wax?
The annual or semi-annual undercoat products like Fluid Film, Wool Wax, NHOU, PFC, and our Undercoating In A Can Clear Fluid Coat deposit an oil film onto the underbody substrates. That oily film does not permit good adhesion with the substrate. Our Black and Clear waxes, and Rubberized, will adhere in areas where the annual undercoat has been washed away but we do not recommend coating over the annual type undercoating with anything other than another annual undercoat like our Clear Fluid Coat. An aggressive power washing that removes the annual undercoat oil film can provide a clean surface that can be coated with our wax and rubberized products.
If your undercoating appears uneven, consider performing a touch-up application to the affected areas, ensuring proper coverage and a more uniform finish. If you have concerns about the thickness of the undercoating, you can also consider using a wet film thickness gauge to ensure consistent and appropriate coverage across the entire surface.
Our undercoatings can be removed, you can find the different removal methods within the safety data sheet for each product. Our Black and Clear waxes can be removed with mineral spirits. Clear Wax can also be removed via Kerosene soaked rag as well. The Rubberized coating can be removed with Toluene or Xylene, vapor degreasing, hot alkaline wash, or low pressure steam. The Clear Fluid Coat can be removed by an aggressive power washing.
Is it normal for undercoating to have a strong odor?
Yes, it is normal for undercoating to have an odor due to volatile organic compounds (VOCs) emitted during application and drying. Proper ventilation is recommended, and the odor is generally temporary and harmless. Consider a low-VOC undercoating or safety protection as options if you are sensitive to strong odors.
How can I touch up damaged or scraped undercoating?
The simplest way to touch up damaged or scraped undercoating, is to start by cleaning the affected area thoroughly, then apply a fresh coat of undercoating using our aerosol canned undercoating. Make sure to cover the damaged or scraped portion evenly, and allow the touch-up coat to dry. If necessary, repeat the process until the desired coverage is achieved.
