General product questions
My product has expired, can I still use it?
We always recommend using the products before the specified expiration date.
Should I use a primer before applying silicone or adhesive?
On a dry, dust- and grease-free surface it is in most cases not necessary to use a primer.

Surfaces can be degreased with Parasilico Cleaner or a fire alcohol, MEK or ethanol.

This phenomenon can occur sporadically and is called leaching.
