Will oil base dye penetrate the super sheen I put on it?

Pro Oil dye is now called Pro dye.  So called oil dyes are not oil based.  They are solvent based and have some oil added to the concoction.  Solvent based infers use of a solvent like alcohols.  Other option is water based.  The stronger the solvent used in your finish, the more likely to see it lift some of the dye, especially water based dyes. 

USMC black is the worst for lifting and spreading.  Good for fixing the toes on your boots, then applying boot polish (wax) over top. 

Your finished wallet looks very nice.  Keep it away from white shirts.

Solvent based dyes will penetrate most finishes.  It will not be as dark as it would with bare leather.  Could take more coats to arrive at same depth of coverage.

I was under the impression that with what we called "oil dye" had an oil based formula for the pigment itself, and that solvents are used as the carrier. Did I have it wrong?

What is best to seal leather after dying it? How do  apply it without taking the dye off? I think I just ruined a project I was working on for a customer when I was sealing it and it started removing a lot of the black dye. I am about to throw in the towel doing leather work if I cannot dye it and the dye stays on when I seal it. I was spraying super sheen but it had a lot of bubbles and I used a sponge to try to spread it out to get rid of the bubbles. Last time I sprayed it left spots where the bubbles were.

hello,

Well,in my work always a basic sentence:  make it simply, and make it as your fathers in ways that have proven their worth.In your case I would have used  bees-wax.And finish with carnuba wax.

nothing else IN MY OPINION.

People prefer generally use ready made products with a label on the bottle/can, i prefer using basic products what i prepare myself and in this case i know exctly what's in the bottle...but it's not politcly correct to talk like that.

Why would you suppose they dropped "oil" from the name?  You can check out their MSDS information on their website.  You can also check several other discussions here on LW where the topic has been discussed before.

Thank you...always learning here!

Here's what I wrote on a blog post recently (and I'm too lazy to retype so copy-n-paste it is), mind you I'm a rank newbie so take it all with a grain of salt. I was talking about dyeing with alcohol-based dyes and how everyone on YouTube vids I've been watching say don't use them and go with oil dyes .... 

Quote

Interestingly enough, those who spoke most loudly against alcohol-based dyes in general were often demoing with Fiebing’s Leather Dye line then recommending Fiebing’s Pro Dye in its place. Fiebing’s Pro Dye line *IS* alcohol-based as well, as per Fiebing’s own website. “New and improved”, but definitely still an alcohol-based dye. 

That led to some head-scratching until I heard Weaver Leathercraft’s explanation in one of their videos — the Leather Dye line has an alcohol carrier with a powder-based dye stuff, whereas the Pro Dye line has an alcohol carrier with an oil-based dye stuff.

Ah ha! It’s the difference between the dye stuff (stuff?) base — not the carrier base — that makes, all the, well, difference in the four bullet points above.

Others probably mentioned this point as well, I’m sure, it just finally sunk in during this particular video. I wonder, though, why Fiebing’s didn’t explain this better on their own site. 

Though I'm still not 100% convinced. Both, per their MSDS sheets, have oleic acid (oil) in the same weight range (5-10%) though certainly their specific % could differ as much as 5%. 

Leather Dye U.S.M.C Black vs. Pro Dye Black ... the Pro Dye does list more ingredients as solvents. And that's about as far as my chemistry lack-of-knowledge gets me. :0)

Fiebing's probably changed the name from Pro Oil Dye to Pro Dye in order to eliminate the general confusion of people thinking that the "Pro Oil Dye" was oil based.

Regardless of the formula and percentages therein, there is a significant difference in performance between the Fiebing's Leather Dye and Fiebing"s Pro Dye.

Most pros and many rank amateurs, like myself, use only the Pro Dye because it is superior.
