Default SEM Trim Black vs SEM Ultra

Has anyone used the new SEM Trim Black Ultra? They have it in matte, satin and gloss. I was going to use the regular trim black as I have heard the old recommended Krylon does not hold up as well as their old stuff. If I try the Ultra, would you go with matte or satin?

I did a post on that Ultra a while back when I got shipped the wrong one. SEM said it is "blacker" than regular SEM trim black & is for modern cars, not our classic ones. I did not try & just sent it back to get the regular.

Thanks Darin. I totally forgot about thread. Now I need to read it and see if you used matte or satin.

Elwood13, why not buy a can or each and try it; then let us know. Couldn't really hurt...(could it?)?

I sent the Ultra back since I had already started with the regular SEM. If I hadn't I would probably have went with the satin Ultra because they say it had an improved spray tip & same sheen, just a darker black. I have had issues with the regular tip "spitting" especially when the can starts to get low.

Okay VJ, I will be picking up a can of each and will take a hit for the team.

So I did a sample of sem color coat satin, trim black, trim black ultra in satin and matte. It was overcast and I need to figure out to take better pictures. I’m think tomorrow I will spray a piece of cardboard with original trim black in the center and the satin and matte on each side and try again.

In person the color coat, original and matte all have the same sheen. The satin does have more gloss. Both of the Ultra paints seem to have a deeper black color.

On a side note, the lady at the paint shop said to to take the spray nozzle off and store the cans upside down. I had never heard that before. She said if you ever sprayed a can and it was hard to push, the paint was dried up at the seal. If you turn the can upside down it will stay wet.

So I sprayed a couple coats last night and one this morning as the cardboard sucks up the paint. This is on a white cardboard box. The ultra matte is on the left, original middle and ultra satin on the right. I didn’t quite get the original in the full middle so it is a little narrower. The matte seems to be a little deeper black depending on the angle. I think I will hold the card up to my leather dash pad and see which looks the best. I believe the satin may have a little to much gloss for a dash application.

BIG difference with the Ultra satin vs regular. Even the matte is way blacker. Thanx for the info on the experiment Chris. Now I know I made the right call sticking with the regular trim black for all the dash. I may try the Ultra satin on the convertible top frame. I was planning on using VHT roll bar & chassis satin on that, but may change my mind now.

I get mine from Oreilly's or Amazon if I am not in a hurry because it is a better deal.

I have seen it at Oreily’s and occasionally at an Autozone but I have found the biggest selection at English Color near me. I know they have a store on Ave K near 75/George Bush but not sure if they have a closer one to you. Also, if they don’t have the color you want, they can you usually have it the next day. Amazon is probably cheaper though.

Thank you for the information.

I think the closest English Color to me is in east Dallas.
