What does MEKP do?

MEKP is catalyst for polyester resin systems. Use only as directed and follow product safety instructions.

What is Q-cell used for?

Q-cell helps create lighter filler mixes for filling and fairing some repairs.

What is Cab-O-Sil used for?

Cab-O-Sil thickens resin and helps control sag or consistency.

Can I use additives with epoxy?

Only use additives that suit the resin system and product directions. Do not assume polyester additives suit epoxy.

Resin additives can be hazardous or easy to misuse. Follow the label and match the additive to the resin system.
