Combinations

[screenman]

When doing combinations we have found that improvements are made by priming the break first with some resin. Here goes, scribe or clean out pit drop a small amount of resin in the pit and flex gently, watch it flow. We even use the vacuum pump over it just a quick suck and release, then just carry on with the repair as normal.
We have found this helps to reduce the unfilled very small legs that show up within the centre of a tight combo in some cases.

I know you can flex through most but not all injectors, but we have found this method to be the best, as we know to get a seal you have to put some pressure on the glass and this method allows the resin to flow before we do that.

Excellent post screenman, but should you be giving all secrets away? LOL

Screenman...you are saying prime the pit before even placing repair tool on the windshield...right? Thanx

I have come on that problme many times and haven't been able to come up with a nice solution so I will surely try this out. Thanks I was going to be asking on here soon now to reduce the visiblility of tight big combos and that may just be the trick I need.

thanks

GGWSR, that is correct. Please make sure when you do this that the repair is protected from uv.

#1. are you useing a thin star resin for this priming step?
#2. Are you a dry vac' guy and does this affect your first initial vac' cycle?
#3. Is this of similar concept to that "crack repair company" that we are not allowed to mention on this forum that uses a priming step before the actual crack repair?( the old guard here know who we are talking about)

I use Magnibond for all repairs, it never lets me down.

I have a mityvac type pump that I use for dry out, after the damage is completely dry I place a small drop of resin into the pit and place the pump over the damage one quick pump up to full vacuum and release this will result in a rush in of resin, then a quick probe around to let more flow into the internals of the damage and then just carry on as usual. I must add that it is imperative that you keep the damage free from UV until you are ready to cure.

I am sorry I am not familiar with the unmentionable companies instructions.
