Montana Colors Polyester Fiberglass Putty is a 2k reinforced putty that doesn’t contain styrene, suitable for repairing polyester composite parts and areas of rusty metal. It’s a creamy putty that’s easy to apply and has great adherence to different substrates. Once applied, it must be insulated with the MTN Universal Polyester Putty prior to painting.
The product includes a tube with the catalyst (to be mixed with the paste in a proportion of 2%) and a basic spatula for users who don’t have this tool.
