michalosixxx Posted August 16 Report Share Posted August 16 Hello, i would like to ask you if there is any way to get rid of micro bubbles that appears at pouring hole ? I am pouring lure with polyurethane resin. After all i am sanding it and even after sanding there are noticeable "craters" in place of pouring hole. There wouldn't be a problem, but when applying the final polyurethane clear coat (by diping) it leaves a rough surface. I attach a photo of a lure after sanding a pour Quote Link to comment Share on other sites More sharing options...
AZ Fisher Posted August 17 Report Share Posted August 17 I use this to fill the holes then sand again, rinse and repeat https://www.walmart.com/ip/Bondo-Glazing-and-Spot-Putty-00907ES-4-5-oz-1-Tube/16927984?classType=REGULAR&athbdg=L1200&from=/search 1 Quote Link to comment Share on other sites More sharing options...
woodieb8 Posted August 17 Report Share Posted August 17 you can use a wood filler like lepages. sand off with 180 and primer. easy fix. 1 Quote Link to comment Share on other sites More sharing options...
swimb8s Posted August 21 Report Share Posted August 21 Also try a very lightly dusting the mold with baby powder before you pour resin ,( not sure what this does chemically but it has helped my bubble problems ) , there are bubbles from mixing the resin, and the pouring hole is the highest point so this where the bubbles collect Quote Link to comment Share on other sites More sharing options...
woodieb8 Posted August 21 Report Share Posted August 21 another note. constricting the sprue and vrnt hole will create a harder body using urethane foams.. 1 Quote Link to comment Share on other sites More sharing options...
