Similar question- I always think of JB Weld as staying kind of gummy.
maybe that helps prevent cracking in the future. Maybe.
I’m good to give Spray.Bike puddy a try.
This Allez has a number of tube dings. Possibly from a bike carrier.
cheers
JB Weld works best above 70 degrees and really needs a full day to cure enough to work the surface. everything has to be very very clean to get the best bond (
Lacquer Thinner}.
I used a gram scale to ensure the mix is very close to 50/50. I worked this project over a week using multiple thin skims as a filler, that's why the fill job looks like tree rings in those photos
What's good about JB is it can be worked to a feather edge without chipping, it can be sanded so fine it is translucent, so no need for spot putty which I hate. So as of an hour ago the frame is in primer and I'm happy with the result. I will let the pictures do the talking.
