Re: dry vac or not
Welcome toab, Good question,
("is this new tech' worth the extra money?")
I watch the market continually and I was intrigued by the theory that resin suspended in the vacuum state would enter a break more readily and there for be an advantage. Some mfg claim to remove all of the air prior to releasing the suspended resin solving the emulsion effect we all deal with on a regular basis. We purchased some of the equipment that you mentioned and while I like the performance of the injectors there is just no magic bullet out there. You have to remove ALL of the air from a break to perform a repair properly and I am sure all of the equipment mentioned in your post will perform this task they are in no way superior to the other equipment out there and if your budget is no problem buy a few and decide for yourself, if not don't waste your $ on a theory that doesn't hold up I mean to remove ALL of the air in a break without replacing it with a liquid is not possible period. Their are some really good systems out there and for a low budget I would recommend others but my best recommendation would be to go with Delta Gm or the like. One says Chevy and the other says Ford. You need to have equipment that will inject resin and vacuum out air, totally fill the void with the appropriate resin and you have performed a repair, end of story. The systems that are doing all the bragging are just hype in my opinion, especially the snip:) I would also say that we use delta and liquid resins injectors. We have eliminated the others that we tested, (EBAY) Good luck in your choice and in business.

Re: dry vac or not
I like the science of lowering the boiling point of the moisture in the repair area with the high vac method and having it leave the repair area before the resin ever touches the repair area as there is no obstructions however I do not believe snippys claim that this will lower the repair time all that much.images/smilies/confused.gif

Re: dry vac or not
also i might add that some of these dry vac systems advertise no hassle vert' repairs which could definitly be handy for those fleet trucks I would like to market to. thanks guys and great forum DELTA KITS. I've been sitting on the sidelines just soaking up all the tips and great tech you guys offer here over the past month and finally decided to join in now. Special hi to repare-brise..I talked to you on the phone before christmas and I was impressed by the way that you shared information with me honestly without trying to sell me . I hope we can do business possibly in the future.

Re: dry vac or not
The LR injectors work well on vertical as do the delta if you go to the local farmers supply and get yourself some cattle syrenges to place the resin in the seal with and then proceed as usual. I don't vacuum moisture as I intend to keep my injecters as dry as possable and I can dry a chip in just a few seconds anyway so to me there is no point in adding acetone or heating from the inside while under vaccume etc. Way to time consuming for me. I use a drystar or torch and no problems for the most part, I did crack out a shield with the drystar one time, it was very unstable and just as I was backing away thinking I had dodged a bullet the thing let loose for about 10 inches. I repaired it and told them no charge but they insisted I take a 20 dollar tip so not a total loss.

Re: dry vac or not
Dry vac can be a good thing, but the claims that are floating around are a cinch to disprove, and you don't need 20/20 vision to see through them. For dry vac to live up to it's claims a few things need to change. The only true advantage to a dry vac system is moisture removal, but it gets complicated. Currently the moisture is removed from the break and moved to the injector, so far so good. The next step is the resin being let into the vacumm chamber, but wait isn't the moisture in the chamber already, well yes it is. So when you put it under pressure the moisture that you so easily removed is mixed to the resin and returned to the break. The commun method of vac through the resin yields the same results. If you want to remove moisture you must go through a vac cycle, remove the injector from the break while in said cycle, dry out injector, and start over with a dry injector, now you have a moisture reduced repair(moisture free only exists in the desert in July). The claims of fast repairs are not due to moisture removal, but high vacumm, but once you surpass 20 inches of mercury the rest is trivial( and many injectors are capable of this even though they wet vac).
Enjoy

Re: dry vac or not
It seems to me that some w/s Repair distributors want to find a way to build a "better mouse trap" which is fine. I think this is done in order to find an injector that is do the repair FASTER and BETTER. One factor that seems to be forgotten is the human factor, a perfect repair never has been and I don't think ever will be soley left up to an injector system. The windshield repair technician is and in my opinion always will be the main difference between a successful repair, with experience a tech will get quicker a repairing a windshield but speed should never take precident over quality.
