What is so weird is it is coming off piece by piece. Scrapes like chewing gum.

No clue. Just sucks.

I am taking back my comment about my friend. Even if he did it wrong, buck stops with me.

I might tint all my resin from here on.

Gonna contact S3.

I've added resin to resin thinking it was hardener.The color is one way to tell but the smell is the sure way.
Got a good sniffer; what smell?

Today I have duratec out there. Whole place stinks of styrene to high he..

Duratec-brushed on. Failed to kick fast. Turned the heat way up n walked away. Double checked-measures were all perfect. Too cool-too thick. Maybe it’ll cure by morning.

Fuzz was talking about me. A friend helped me glass in my sole, a pretty big job on an OD 18. Him mixing, me spreading and wetting out. Next morning...syrup. looked on the table and saw a jug of slow and fast hardner next to each other. Was out of cash at the time.

Same guy helped me sand the primer on the outside, him working one side, me the other. Just rough it up so the paint will grab... I'm half way down the port side and he's still working up on the starboard bow. I walk around to see what's taking so long and he's down in the glass in several places!

Having friends help is awesome and lots of fun...most times :roll:

I spoke with S3 and we mutually agreed it was a stirring error. That was me. I was in a big hurry and dumped it and said I’ll mix in the tray and then forgot.

Memories...

For my project, I was considering using pigment. I saw a Robert Perry build where pigmentation was a spec of the yard.

So yesterday I contacted Systems 3 on it and they sell the pigments. There tech support person was covering for the guy on vacation and well, bless her heart, I was a pain in the ass customer.

Things were going sort of okay until I read an S3 whitepaper on their site that said I could not add any thixotropics to Silvertip. I nearly had a heart attack. I called her back; poor thing. She called john b at home and he told her only not milled glass. Of course I have used milled glass with Silvertip for all my repairs; so I got no comfort there either.

At this point Inam chalking it up to marketing schmucks.

She told me I’d have to experiment with the pigments?

Anyhow, I am a little sad I was unable to get the pigmentation understood.

All I learned is you can add pigments to the resin at no penalty; to 10%? I would NEVER add 10%. The stuff is 11.50 for 2 ounces.

So, at least you would theoretically see if you forgot to stir. But the gal over at S3 couldn’t grasp that concept. I think she assumed due to lack of experience when you poured the two together they would turn color? Not sure.

Anyhow, if anyone has done pigmentation for qc, let me know.

And I’ll send you a link to the heart damaging whitepaper Jeff and you can let them know theu ought to be nicer to customers that buy 10 grand in epoxy. And yeah, I’ll need more.

Question: if you add X% of pigment, does it reduce the % of other additives you can add?

Stated differently: If I'm planning do add graphite at 10% but I add 0.5% red to ensure mix, is the percentage of graphite limited to 9.5%?

I think of those as 2 different addatives. The pigment is a chemical that combines with the resin, the graphite is a solid that gets encapsulated by the resin. You shouldn't have an issue adding as much graphite as needed. However with the pigment, if you add to much it can effect the strength of the resin. 0.5% is pretty minor amount so I wouldn't worry.

You need the hardener ratio correct.

The ratio is applied to the completed mix.

So 60 ounces of epoxy or 20 h and 40 r and then you add the pigment. But not 10%! Nuts!

Let’s cost out the epoxy at 128 dollars a gallon or a dollar an ounce. The pigments are $5.75 an ounce.

For the 60 ounce mix; epoxy cost is $60 and pigment at 10 percent is ! $34.50.

Ain’t happening.

There is some rational way to use pigments for quality control, but S3 told me I had to make my own plan/test/experiment. If you run at 1/3rd of a percent; cost is about a buck in my above example.

The additives are always in addition; not as a reduction. Now, if you are running excess usually; might be a chance to cut back cuz you have excess material. But dry fabric is all bad; so only if it ain’t wetout.
