Epoxy Putty

[swimb8s]

Hey Guys.

I made some swimbaits , got them balanced with correct weight and then used epoxy putty to fill in the holes. Painted baits and tested them . When I looked at them about four hours later I noticed that the places I used the putty had shrunk creating craters . Anyone know what may have caused this ?

Thanks

Tommy

Hey Tommy - this question really belongs in the other Hardbait Discussion forum not in this How To section. Notice this is section shows how to build or do something. You might get more answers if posted in the other section.

You didn't say what products you used so it will be hard for people to pass along what they learned from experience.

Seems to me the epoxy putty might be interacting with the top coat and shrunk. Try letting the putty cure more e.g. give it more time to set. Try an experiment on a scrap board, drill holes, fill them with putty, and cover some with finish and some without. Put the finish on a couple at different times. You could try different finishes to see which one might react or won't react. Maybe try covering the putty with a thin layer CA glue after application but before finishing. Just a thought.

I use bondo over the weights after they are epoxied in with D2T. Its a lot easier to sand down than the epoxy putty.

I use epoxy putty quite often and never had this problem.  The stuff I use (whatever brand Home Depot has at the time)  hardens in about 5 minutes and whatever the shape is at that point - it's what you get and doesn't change.  The putty is quite hard when cured so I don't understand how it could become dimpled afterward.
