lurebaz Posted February 27, 2017 Report Share Posted February 27, 2017 Hi, Has anyone ever had trouble with blisters or raised spots on urethane lures? Every so often (and without warning) they will apear on a lure, sometimes weeks after completion. I will explain my casting technique - I try to only cast the blanks on non humid days The micros are stored in an airtight container I vacuum the resin/micro mix I use a slow set up urethane 9 min pot life I pressure the molds to 70 psi and leave for 12 hours under pressure Once de-moulded the blanks are cleaned with de-greaser The blanks are left to fully degass for 2-3 weeks. I use a urethane primer i paint mainly with Createx I topcoat with envirotex lite I have often thought it must be trapped air escaping from the body but if i cut through the lure in the effected areas there is no signs of bubbles. Can anyone help as it is driving me crazy. Many thanks Quote Link to comment Share on other sites More sharing options...
