Sanded factory primer (not on large areas of new parts that have been sanded and coated with KTL primer)
Thoroughly sanded old primer or factory primer (excluding thermoplastic coating)

Because of the wide variety of alloys and manufacturing processes for metals, the base surface must first be tested to ensure that the pre-treatment provides sufficient adhesion.
   
Pre-treatment of base surfaces:
–  Carefully clean using Silicone Remover -LVM 020 000 A5- or Silicone Remover, Long -LVM 020 100 A5-.
