Windshield Repair Forum

Today i did a job it was a small starbreak it did good but were i drilled the hole for the resin to flow it never filled the hole all the way i could stick a small pin in it about half as deep as i drilled. Then i tried pit filler no good then more resin and still no help what is going on help

Try creating a bullseye in the chip. Take your probe and stick the tip into the hole and gently tap the back end of it, it will create a small bullseye in the chip. That might help you.

Don't know if i understand your post correctly. Does the resin pull out with the curing tab when you remove it? If so you may have a water repellant product on the windshield. Alcohol will remove the repellant.

A water repellent product can cause this to happen. Another cause may be that you are not curing the pit filler long enough. If the resin inside the drilled hole is still soft, the action of the razor blade will pull it out. Try extending the curing time, especially if you are using sunlight rather than a curing lamp.

A lot of variables here in regard to "did you do this" and "did you do that" which are unanswered in your post.

Sounds to me as though the star itself cleared up but a pit-hole was present after you pulled the equipment.

That could very well be due to what some of the other answering posts suggested. (Inadequate pit filler cure; water repellant...).

It could also be due to insufficent resin or a number of other possibilites depending on circumstances.

You might want to go into more detail as to exactly how you effected the repair, jackmac.

How large was the repair area and how many drops of resin did you load?

Did you cure under pressure?

Did you use a UV lamp or cure under strong sunlight?

Your problem is interesting and I hope you decide to expand on the technique you used. I'm sure that Someone on the forum can then figure out what happened.

yes the star did clear i only used 5 drops of resin in it. the star waz very small only like 1/4in tip to tip i have an aegis system and use delta premium glass bond and a uv lamp for 2-3min i allways clean the windshield with glass cleaner before a job.

Sounds like you used plenty of good resin; good equipment and did everything correctly.

If you cured under pressure, I sure can't explain it, jackmac.

My ex-wife always said I think I know it all.

I'm sending your post and my answer to her just to prove she was wrong.

Anyway, I'll be interested in some of the other explanations for that remaining pit, for sure.

i always put the glass cleaner on a paper towel never wright on the windshield i may start to do the cureing under pressure thing on the next one to see how it works thanks to all.

did the pit filler stick to your curing tab ?if so there is rain repellent on the glass. clean it, i prefer lacquer thinner or denatured alchol.

no the pit filler did not stick to the curing tab that is what got me i think that i may have pulled out the resin with the razor when i scraped the windshield i used it at an angle cutting into the repair and not stright up and down across it
