    • Common Questions

    Q:

    Is it safe to apply this to bare metal or should the surface be primed first?

    A:

    I've applied it to both surfaces and it works well.

    Q:

    Is it made of polyurethane caulk or something else?

    A:

    The material information system can be found here: Synthetic rubber.

    Q:

    What is the ambient temperature range recommended for applying this seam sealer?

    A:

    I would always recommend against it.

    Q:

    Is it paintable?

    A:

    I sprayed using a 2 part paint and took fine, but the seam sealer was allowed to dry/cure for several days first.

    Q:

    Is it thick enough to hold on to a vertical panel without it running?

    A:

    I used it on a drip rail on my 70 pickup and it works great, it spreads like thick liquid nails.
