Windshield Repair Forum

I'm having trouble with the pit resin staying put (after curing) in some pits and deep wide scratches. I'll appreciate any suggestions..

Although that is not what pit resins are designed for, you can increase your success rate by first wetting the break with premium bond.

Thank you. Would you also use this procedure when trying to fill a large pit before the Bullseye type damage? (I have one to do tomorrow).

Something I notice with some of the larger entry wounds. After scraping off the cured pit resin the pit is opaque and polishing with pit polish doesn't help much. Just did a combo today. It filled very nicely, but the pit, although smooth was dull and opaque. I use Delta pit polish applied with a paper shop towel. Any suggestions. Thanks. Ben

I use a cotton or felt wheel on the dremel tool for polishing, for me 5000 rpm's does a better job than a paper towel.

fxstdi,

The pit will always be somewhat opaque. Make sure to use a brand new razor blade each time, and only scrape until the edges of the pit show. The more scraping, the more scratches in the pit. Hold your razor blade straight up and down, perpindicular to the glass. Pit polish will help quite a bit, but won't make the pit completely go away.

Feel free to try CPR's trick, but every time i've tried it, it leaves the pit slightly concave...Again, just my observation.

Not sure I understand, could you explain?

CPR/Jeff,
Thanks for the suggestions. I'll experiment. Ben

We always scribe the resin into a pit before applying pit filler to promote adhesion. Scratching it in will help some but I always tell our customers that it is not an actual repair therefore no charge and we will be happy to reapply as needed, "stop by any time". (We find chips the customer wasn't aware of that way). Wsr is a service industry, I find that if you go the extra mile people remember!

We also stop scraping a little prematurely on the pitfiller leaving a small amount (hump) over the pit and polish it smooth with pit polish. You get a better finish that way. Scott

For the small pits and such, I apply the resin just above the dammage and work it in with my probe. This promotes adhesion(I have not had a come back for re-application, we also do pits N/C). As for large pits I apply the pit resin in the regular manner, scrape, then re-apply a small drop of resin and work it into the previous resin using a curing tab(place tab over resin and move around with pressure), cure again and re-scrape. This clears up the surface a little better, follow up with pit polish applied with a dremel on low speed, but not for long, 2-3 secs max.

Merci
