I never let it dry....always kept it wet the whole time..

Killing cancer is a tough proposition, and never quick.

The data sheet is not very clear. They don't tell you to leave it wet between coats or to let it dry looking at it again.

I'm going to brush a third coat on right now and call it a day. Hopefully it's black tomorrow when I take a look at it after work.

The only danger in letting it dry is that the next coat needs to soften the previous, which lessens the time the product 'works'.

From your experience when does it turn black?

I just read the TDS...nowhere does it say to let it dry. In fact it says to keep it wet.

I think that's your problem.

I think a phone call is in order... [evil]

Argh. This is the tds I got from SEMs website -

I'm not seeing where it says to keep it wet. I take the note about 1 heavy coat being slow drying vs 3-4 light coats. I take that to mean light coats dry faster vs heavy.

My guess would be blocking the oxygen needed for the conversion to black oxide.

If you are not happy with your results, I have used Corroseal on wrought iron with good results.  Might be different with sheet steel.  The ingredients are glycol ether  acetate and latex.  They claim you can top coat over it without primer.  I got my Corroseal from Moss Motors.  My thought is if it works on old rusty British cars...  I aiso hear good things about Eastwood Black Rust Encapsulator.  Then again, if it is a top coat as well as a converter can you tell if it worked?

This is what I'm reading on the SEM site... https://semproducts.com/public/content/techsheets/sem_tds_rust-mort.pdf

BRUSHING:
Apply multiple coats, keeping the area wet with Rust Mort until all rust is converted or removed. The longer the
surface is kept wet, the better the final result. After completion, remove any excess or non-converted Rust Mort
by rinsing with water and a brush. Make certain all surfaces are completely dry before proceeding with body filler
or primer per manufacturer’s recommendations. Failure to remove excess material can result in loss of adhesion of
subsequent top coats. Limit exposure after drying the surface to eliminate flash rust.

No clue...

I'd recommend cleaning off the dried product, and use it like it states in the TDS I linked to. I've used the product before, and it works if you keep it wet, and clean with water before it dries.

Just got an email back from sem tech.

Apparently rust mort is designed for heavy rust. They said with surface rust it very likely will not turn black.

I was advised to wipe it down with a wet rag before applying anything over top of it.

Sounds like I'm okay.

This is the primer they sold me. I asked for urethane and I don't see that word anywhere on this can or on the TDS for this product.

You don't want to hear what I think.

Course has already been corrected.

Side note- the tech support number for SEM is funny. They don't even bother trying to answer they just outright tell you we're too busy to answer the phone right now and to leave a message.

I also sent an email into tech support which they did respond to fairly quickly. I have not gotten a call back.

It sounds like this stuff wasn't really meant for surface rust even though you can use it in that application. Looks like it's meant for heavier rust that's beyond surface.
