I'm just gonna get new carpet, it's the weird cloth inserts in the middle of the seats I'm working on. It's almost like a burlap-ish material. I'll post a pic.

I tried the Plasticote Buckskin...not even close.

Hi Roadcaptain S3. I'm in the same boat. I spent the better part of last year looking for a paint that would be the right colour and found nothing! I mean NOTHING that was the same. I finally decided that SEM was the best product and got what was close Santa Fe 15123, it's the colour from '75. In my case it will match the colour of the vinyl from the buckets and bench I have from a '75 Malibu.

Thanks for the picture of the front bench. It's very nice looking, not to mention I was going to paint my belt buckles, but yours are chrome. Looks better that way.

I've got SEM buckskin on the way. I'm if that doesn't work, I'm going to try VHT buckskin and/or SEM Palomino and i"ll give your suggestion a try as well. Thanks.

I've been looking at various threads from C3 vette forums and mid seventies Chevy trucks. It's wild how many variations of tan and brown that GM used in interiors those years. It's hard to tell the difference between Doeskin, Buckskin, Lt. Buckskin, Sand and Saddle from one year to the next. All very similar. I've decided to just get several different dyes and try them out side by side until I can figure out which is closest. Fortunately, most of the ones I'm trying are $10 a can or less. I'm sticking with Duplicolor, VHT and SEM because I've used them all before and had good results.

Once I figure that out, my plan is to do the seat inserts, console and carpet in the same shade. I've never dyed cloth or carpet before so it should be fun to try.

If you are doing a hole interior go to your paint supplier and ask them to mix up the SEM color you want in a Qt can then you can use a regular paint sprayer gun to shoot it all one time. This is what I did with mine but I had them mix me a color to match my leather. I also sprayed clear over them with a flattening agent in it for right sheen to it. I would just go with the SEM paint rattle cans if you are just doing a few pieces but a whole color change this is the way to go. You don't have to do the clear coat I just wanted to try it.

Thanks Wally, I'll try that route.

I'll likely have to take the columns somewhere and have the new one painted to match the one coming out, so maybe the body shop can recommend someone locally that mixes that kind of paint. I can't find anybody within forty miles that will.

Forecast is for single digit temps this week, so I won't be doing any actual painting for a while yet. I still have to strip the interior and weld some brackets too.

Your welcome.
Its -4 below here right now. Looking a deep freeze this week.

If you get a can of SEM that is a good match they sell it by the QT at summit racing.

If you cant find a local paint supply to mix it up for you. Mine is interior plastic paint they mixed but was to flat like base coat for auto paint so they put too much flattening agent in it. so I mixed up some clear with my own flatner in and sprayed over. Much like a base coat clear coat paint job.

Yes I have those Fisher Body Manual Blues. They cutely identify the three types of interior plastic: ABS , polypropylene and vinyl. Then they promptly throw a curveball saying BTW some of the vinyl is really ABS plastic with PVC or vinyl mixed in. Sigh.

Is there some listing somewhere of which A body interior pieces are exactly what kind of plastic? Thanks for any info.

I'm starting the cleaning process for the base trim door panels for my sedan. On a couple of them the top part is somewhat worn. I will paint over of course but the texture won't be there. There is a SEM Texture paint SEM 39853 Black Texture Coating Spray but I can't find info about where in the SEM cleaning and prep process this would be applied? I have only used the SEM Soap thus far and the panels needed it as dirt poured out until 3-5 soapings were performed.

Anyone have experience using this? Or is something else better?

-----
Also a different question. The top section of the door panels has a curved portion with the door lock hole attached to the decorative section below it . I never noticed before but the two sections became detached on two of the door panels I'm working on. There doesn't seem to be any fastener holding the two parts together. It just seem that the lower portion is wedged into a plastic binder. Is something missing or is there some better way to bind the two sections together. NOTE: I an not talking about the separate hard plastic bottom section with the arm rest. Just the upper section that sits above it,

Ive never used SEM texture paint. I have used various "chip guard" paints on rocker panels. They came in various types of amounts of "chip". Some being more subtle and some more aggressive.

I took a look at the 39853 tech data sheet and it doesnt mention any specific prep steps beyond scuffing the area. https://semproducts.com/product/texture-coating/39853

Personally, Id follow the SEM prep steps for their interior paints which includes their "soap" and then the "cleaner". Cant go wrong with those cleaning steps. I also use a grey scotch brite pad when using the soap just to give it a bit more grit. The color tech sheet is at the bottom of this page. https://semproducts.com/product/color-coattm-aerosols/aerosols

by 76Chevelle2Tone Thu Apr 25, 2024 11:15 am

Yes I am following the steps outlined on the previous page. I just couldn't figure out whether the texture paint would be applied before or after the vinyl prep. I don't know whether the texture paint interferes with the adhesion and color coat but I can't apply it last since it only seems to come in black.

I suppose I could Frankenstein the door panel uppers with a better top portion attached to the decorative part of the upper panel. I am just unclear how the two parts were put together as I don't see fasteners.

by Joe73 Thu Apr 25, 2024 11:52 am

Id clean, then texture, then color. Need cleanliness for things to adhere properly.

by 76Chevelle2Tone Wed May 01, 2024 1:48 pm

I talked to a tech at SEM Paint regarding the Texture paint and specifically when to apply. Here is his response:

"After cleaning, you will want to use the correct adhesion promoter and apply the first coat of color and let that flash for a few minutes, then apply the TEXTURE COATING from a distance to create the texture you are looking for. Since it is "dry sprayed" on the surface, that first coat of color will give it a tacky surface to grab onto. Once you have the texture to your liking, it is usually dry enough that you can apply the color over it to lock it into place. "

Hope this helps users.

I don't suppose the tech expanded on that?

by 76Chevelle2Tone Thu May 02, 2024 10:43 am

Zucchi,
In my question I had just copied the info from the previous page of this thread which seemed to be correct BTW when I studied the SEM product notes. SEM Sand Free is used with ABS, PVC and other similar plastics while TPO, EPDM, PP and other similar thermoplastics require SEM Adhesion Promoter. It is based on the acetone test. I assume most of the plastic in the A bodies is the first type?

by 76Chevelle2Tone Sun Jun 23, 2024 5:44 pm

I found this on the V8Buick site for 72s (copperhedgs1). If there are differences with our G3s please advise. Thought it might be useful.

The interior plastic types are

1: hard ABS plastic(Automatic console, steering column lower filler, rear windshield lower corner pieces)

2: Soft ABS plastic(dash pad, bucket seat headrests + urethane leather repair)

3. Polypropylene plastics(Kick panels, bucket seat backs and bottoms, door arm rest bases)

4.Vinyl plastic(headliner trim windlace, door edge windlace bead, coathooks)
