Unconnected leg

[Mr Bill]

Sometimes I do a repair on a star chip where there is an unconnected leg. I normally drill at the point of impact and then pop a bullseye to connect the unconnected leg to the main body of the chip. Sometimes the very end of the leg will not fill.
I have tried applying a little heat from the drystar and flexing the leg, but the very end of the leg still will not fill.
Other than moisture removal; any suggestions?

Sometimes I can get them to connect just by flexing from the outside of the shield near the impact or were you can see the crack starts. Sometimes it takes quit a bit of pressure were it is almost scary about a crack out but it has never happened yet LOL

Mr Bill are you sure there is absolutely no chance of premature curing going on, we see this as a major problem a lot of the time, even with the UK weather.

If premature curing was the culprit, is there still a way to fill the end of the crack?
I didnt use my bubble on that one and just used a dark towel, but removed the towel when I applied heat, so I could see what I was doing.
I repaired another chip, using the bubble on the same windshield and it turned out almost invisible, just a litle light distortion.
Anyway, I will be sure to use the bubble in future.

UV will cause the resin to thicken very quickly, for the resin to flow to the end of fine legs this is something we do not need to happen. If it has cured teh I would suggest the only option is to drill and pop. Thank you for being honest in the way you carried out the repair, quite often when we post what could have been a mistake on the part of the tech they deny it, this lesens the oppertunity for some one else to learn.

If in doubt dry it out, keep UV out till you are 100% sure you want some in there.

I have suggested this small test many times on here. Please try it sometime.

Place a small drop of pitfill under a tab, even on the shaded side of the car and watch it set. We prove this in our training by placing the pitfill on a window outside where the students knows there is no chance whatsoever of any sunlight getting to it, you will be suprised at the amount of ten year techs that did not know about this problem.

I know just what you mean about an unconnected leg. About once a month or so I'll get a leg that fills about half way and stops. When this happens, there are really two cracks that look like one. If you would magnify the leg you would see that one half stops before the other one starts.
Slide your injector to the side and drill a shallow hole right where the filled part of the leg stops. Try tapping the drill hole, sometimes this will join the two halves of the leg. Put pressure back into the original puncture hole. If the leg doesn't start filling, drill the new hole deeper and carefully pop a bullseye. Put your injector over the new drill hole and fill the rest of the leg.
