What should be done after applying structural foam?

After applying structural foam, the best course of action is to reinstall components after priming them with appropriate coatings. This is crucial because structural foam is often used to restore strength and rigidity to a unitized structure, providing essential support for various automotive parts and panels.

Priming with the right coatings enhances adhesion and protects the repair from environmental factors such as moisture and corrosion, which can compromise the integrity of the structural foam. It prepares the surface for subsequent layers of paint or finish, ensuring durability and longevity in the repair.

While allowing the foam to cure without further treatment might seem appropriate, it doesn't address the need for additional layers that provide protection and adherence for other components. Sanding down the surface might not be necessary or advisable due to the possibility of damaging the foam or creating an uneven surface. Leaving it exposed to air for drying can also lead to contamination or degradation of the foam's performance. Reinstalling components after proper priming is essential for creating a successful, long-lasting repair.
