evercoat quantum filler

I tried it, sands nice. The version I tried came in a caulking tube but halfway through the tube the mix ratio went bad-must have been an air pocket. I didn't see enough advantages to switch and don't know of anyone else using it. If I remember right you could get it with two different hardeners-temp related?
 
Yup-same stuff. I know at the time the cans had been out for awhile and the store where I was buying some Rage Gold filler was including a caulking tube of the stuff as a promotional item. I haven't seen anyone stocking the tubes though just the cans now.

Quantum1 also passes 500 hours salt spray (ASTM B117)

Which would be its claim to fame, and would presumably make the step of epoxy before filler unnecessary.

I'm not sure I believe their claim, though.
 
Yeah i've used a couple bags of it nice product for sure. I've used it over@ bare metal and epoxy and adhesion to epoxy was awesome and feathered beautifully. It damn expensive though. I've been using z-grip instead over epoxy and i'm just as happy.
 
being an epoxy hybrid is why i'm interested. i would like to get away from polyester all together. guess i'll order some and use it on edwards 37.
 
Shine, you're going to like how it applies and sands, adhesion is also really good. The mix ratio is important. For me I didn't see anything magical and I don't have problems with polyester so it wasn't worth making the switch IMO.

I seen a 3M bondogun demonstration awhile back and the rep did a good job overall but there were some salespitch comments that weren't logical, interesting though. I had to laugh when he said there was an optional holster for it. Still don't know of anyone using it but it sheds some light on what products are being developed for marketing. I expect if the Quantum filler sells well the rest of the filler suppliers will develop epoxy based fillers-it's all good. Maybe they'll develop a high build quantum primer surfacer-epoxy.

Not that there's anything wrong with polyester, right?
 
barry can correct me if i'm wrong but it is my understanding that in the world of resin epoxy is #1 followed by vinylester then polyester. vinylester being a hybrid polyester/epoxy resin. polyester is the weak link . it has poor adhesion qualities , shrinks the most and is known to absorb water . i cant help but believe this would be true with fillers also but i could be wrong about fillers. i just don't trust polyester . this why i chose to go epoxy only .

just one ole fat farmers opinion on it and worth exactly what you paid for it......
 
I agree with you...however it is the best thing available now, and is a 50 year improved everyday product. I think these learning painters and bodymen (me included) need to know that every good paint job that they have ever seen, every show quality, Pebble Beach, SEMA, magazine car that they have lusted after to duplicate, is loaded with copious amounts of polyester in all stages of the job to achieve their look. Does epoxy have better adhesion qualities...yes...but polyester sticks just fine...proven....does it shrink, yes, figure that in how you use it and buy good quality and USE IT RIGHT...the shrinkage isn't a problem...does it absorb water...maybe...keep the water out of it...I think you got burned by one brand of polyester (which we both agree is crap and shouldn't be used) and have been on a campaign to distinguish polyester entirely...I don't disagree, but there needs to be something better first....there isn't...by the way, epoxy has some problems too...I'm just sayin'...but I still think you're the best, Shine.....
 
yep, we're kinda stuck with it for now. hoping the new stuff will be a little better. to be honest i think most problems are because of mfgr cutting cost and using cheaper resins and such after they establish the market. much like they do with clears and such. as for dynatron bondo corp they can kiss my wrinkled up old butt. i threw away everything i had.
in the future i plan to avoid needing filler at all. will do the build with epoxy resin and mat . maybe a skim coat of this new hybrid.

i always thought vinylester was the holy grail of resins until i started to research the epoxy . what i found was that it is the best for making parts ahead of polyester. i guess the viscosity of epoxy makes it hard to use for molds.

great , they are coming out with all this great stuff just in time for me to retire .

thanks for the kind words fly......
 
I'm honestly skeptical of how much epoxy the quantum has in it. Obviously you cant come to a 100% conclusion by msds sheets...but the msds sheet on the filler itself, there are no epoxy resins. The epoxy resins are found in the hardener. So you have a 10:1 ratio of filler and hardener....the epoxy being that "1" in the ratio. (according to their mixing instructions).

I'm just not so sure that really counts as being "better" than what he have availabe now with polyester. Especially when you consider price. I think a gallon is on par, price wise, with rage...but you have to buy the hardeners separate. They list from $4 to $6. And i dont think 1 tube will get you through the entire gallon.
 
price is never a deciding factor with me. quality is. example being the piss poor products sold by dupont and ppg that they call paint. price would be ok if they were worth a damn.
when dealing with chemical mixes volume is not exactly the issue. what it does is . maybe we can get barry into this with his knowledge of resins.
 
same with me. I'm no chemist...so i really cant justify charging double the amount for a "hybrid filler" that may not even be better than what we have already. Anything those sales rep throw at me just goes in one ear and out the other. I really dont hear of a lot of guys using this stuff so makes me wonder if it is really worth anything. I tried it a while back and at first i was sold on it. But the more i used it the more it got me thinking....is it really better? Polyester filler has never let me down...i do all my work over top epoxy so the salt spray test i could care less. It isn't a "pinhole free" filler and isn't a "1 step" system like they claim. I can use marson platinum and any pinholes i get, i can spread it tight enough to use it as a "glaze" to finish out. I always refer to the guys across the street because they are high volume, stuff cant be found in there...so it really isn't geared toward high volume collision work. No one else i know uses it. But enough talk about collision work.....

So all we are left with is adhesion that they claim is so much better. Shrinkage would factor in also. But this being a hybrid and not a true epoxy, is it really THAT much better. Does adding epoxy in with polyester improve the product? As said above...i'm ignorant when it comes to chemistry..LOL. It certainly sounds good in advertising...but we know thoese are 2 different things.
 
something i learned a long time a go. stop getting pinholes!!!!!!!!!!!!!! find out why you are creating them and stop it. they are next to impossible to fill with filler. it traps air in it and just leaves a void . i'll rub epoxy into one if i find it but never filler.

tip. keep your filler warm . it helps release gasses .
tip #2 never ever judge anything by a collision shop.
 
The very basics of polyester/vinylester resins and epoxy resins don,t mix....at least right now...Quantum is a gimmic right now....save your money and use Rage or 3m...dish your pinholes with a hand spun drill bit, just oversize, then fill...Taper is everything in polyester....this is a good discussion, I think...
