Drill Holes

[mobilerockchiprepair]

I have read countless messages on here about drilling or not drilling. I was instructed to drill, so I have been drilling. However, I cannot for the life of me make a drill hole disappear... Is it possible? Thanks for your time, Jon.

Hi, drilling should ALWAYS be seen as a very last option. In our opinion, you always should attempt to fill the break prior to drilling a hole, no matter how small that hole may be, the repair will always be more noticeable. Time should never be an excuse for drilling, in fact that is a pathetic idea. Try flexing, heating etc prior to your drill.

Hi.. I really don't think a drill hole is that big of a deal as far as cosmetics
i've never had a bad comment on them .. a pit is a pit some big /some small
patience is a good virtue though.. it is amazing when you have a star that
doesn't fill as fast as you would like.. just walk away for a bit and when
you come back its GONE !!! anyway there are times when you must drill
a line.. finishing a repair is so important ...i've been seeing too many
that someone just didn't take their time to finish:)

Heat before drilling??? I disagree with that option

When I finish the repair, I remove the injector. Drip pit resin over the top of the hole and let it run over it. Apply a square and cure. When I shave the resin off the hole is always still VERY visible... Is there another approach that I am not doing? Thanks, Jon.

Your doing nothing wrong... a pit is a pit ... they will never go away
wsr is repair!! not a new window ....

You might try using a smaller diameter drill bit, the smaller the bit the less noticeable it will be.

Make sure the drill hole is full of resin before curing. Curing before adding pit resin will also help reduce the visibility of a drill hole. Any air that tries to escape during curing will be caught under the pit resin at the highest point(the drill hole).

When is a hole not a hole? When it's filled in.

You also need to follow Repair1's earlier advice. That will greatly reduce visibility.

Thanks for all the advice guys. One last quick question. When shaving, should I shave the resin ALL the way off, or should I leave a little bit and polish it clear?

Depends on what you are using for polish and pit fill resin. The resin/polish I use works best when the resin is shaved down to the glass, some I have tried are best left a little proud, as the polishing process wears away a little of the resin, leaving equal in the end. If you are ahving problems with your pit being overly apparent. I have a few suggestions. First try filling in layers, if the resin is too thick you may get air coming up through during curing, filling in steps may help this. Make sure that the pit is filled befor polishing, look for air bubbles, it there are some you can use your pick or drill to pop them and refil them with resin, cure and continue, If the pit is big scrape off the first layer then apply another small amount of pit resin, then put a tape over it and press down on the tape to work the resin into the previous application, scrape and polish as usual. If your pits are not as clear as you like try another resin or polish, not all are created equal.

A few other tips, take the time to properly cure your resin, it may be hard on the surface, but requires a little more curing down deep(in the drill hole). Make sure you don't shake your resin bottle, some people have the habit of shaking a bottle before opening it, while good for paint it's bad for resin) this induces bubbles into the resin, causing countless problems afterwords(I had one of my techs that was quickly broken of that habit).

Enjoy
