Two pack polyester body filler

P40 is a two component polyester fibre filler used for bridging of holes, gaps in steel, fibreglass and most plastics.  It has many times the strength of regular fillers.  Clean the area to be repaired, mix resin with hardener, apply so that it is not quite flush with surface.  Ready to sand in 20 minutes.  Finish off with  P38, the polyester filler for a professional finish to be primed and painted.  Pack includes resin, hardener and applicator.  Comprehensive instructions are included.

Many of the Australian bogs won't work with POR-15, they just fall off. We strongly recommend the use of P38 and P40 for a correct lasting job.

U Pol P40 Body Filler is specifically designed for applications that require more strength, such as bridging holes, or filling high-stress areas. U Pol P40 Body Filler is loaded with tiny polyester fibres, which makes it many times stronger than ordinary body fillers. Use U Pol P40 with POR-15, to make permanent repairs to rust holes or deep pits in steel or galvanized steel. Then, use U Pol P38 body filler to finish off the repair for the ultimate smooth final finish.
