Please forgive me.  Are the interior panels plastic or are they considered vinyl?

SEM recommends using their soap 39362 AND surface cleaner 40404 AND prep spray before painting but I need to know if I should buy the vinyl or plastic prep spray.

I know prep is vital for painting.  Has anyone used SEM paint for interior panels?  If so did you use the soap and surface cleaner and prep spray?  It also looks like they have another spray you use right before final using the SEM black landau paint...its called SEM 39133 Flexible Primer Surfacer. 

Thanks.

20+ years ago SEM recommended wiping panels down with Enamel reducer... I suspect the Landau Black formula has changed since then... But the original stuff has held up very well...

I've used SEM products with good success.  I clean my panels with a good soap and dry them very well.  The SEM paint has always held up super for me.  I like their stuff a lot.

I usually use soap and water, sometimes a power sprayer. 
Depending on what's left on the panel I have used Xylene as a cleaner. 
Then I use the flexible primer.
Then color. 

Works great and holds up pretty good over time.

I have used the plastic product, not familiar with the vinyl product.

You need to use SEM's Adhesion promoter as well in my opinion. :alan2cents:

SEM makes some of the best products in the autobody industry!!! to answer your question the panels are plastic.

Thanks everyone.  The quick accurate responses given are amazing.  This site is really helping my project move along nicely. Thanks again. 

So the order of operations would look like this:

1. Wash well with soap and water and let dry thoroughly....Just use something simple like dish washing soap and warm water?

2.  Use SEM plastic adhesion promoter

3. Use SEM flexible primer surfacer

4.  Lay down some SEM black landau

Sound good?  Should I lightly sand the panels at any point or NO?

Thanks

thin or light coats also. if they are to heavy you will lose the grain.

@MoparDave (https://forum.e-bodies.org/mlist/mopardave_10) does Metro sell paint that matches their panels ? I have new blue door panels but need to do convertible rear panels the same colour  :thinking:

I did all my interior pieces with the Adhesion promoter and then the Landau Black.  Didn't need/use any primer.  They all came out looking like new.  But then I wasn't changing colors either.

I recently used the soap, adhesion promoter and color with no issues. I have no plans to change the process for the remaining panels I need to do.

at one time I believe metro did have some color matched paints. with them being out of the bizz for this long I doubt he would have any.

I've thought about doing that too.  The Metro panels have a slight matte finish / sheen to them compared to what I think they should be.

I was kinda wondering about this. I have a full set of metro blue panels and recently used Herb's on a lot of other pieces. Herbs matches the original pieces almost exactly based on some areas that didn't get sun faded ..... but the Metro panels don't have the same sheen/tone .... so should I use Herb's on the new Metro panels too, or should they stay a little different as an offset??

This is great information!  :bigthumb:

Ressurecting this thread rather than creating a new one.

I'ma bout to order two door panels for my challenger. They need to be burnt orange.

Has anyone used Herb's system before? It seems to be the only way to get burnt orange on a door panel?

I take it that for the OE look, it does not need to be cleared?

I used Herb's Pearl White.  It turned out nice.  I changed some black seat hinge covers to white.  The Pearl White just changed the black to a silver color.  I had to spray them with SEM white first to change the color...then but the pearl on top.  If you are spraying black door panels, test a small section first and see how the coverage is.  You might have to put a base coat of somethings else down first.  It just depends on how well Herb's burnt orange covers. 

Once the burnt orange is dry, you can determine if you want to spray a clear or not.  SEM has a matte clear and a gloss.

Old thread I know but what I would do is just mist a clear over them.  That should "up" the shine a little but not change the color.

do the test spray on the backside where no one will see it if it doesn't turn out right.

I have only heard positive comments regarding herbs paint.

Herbs is great stuff. I really liked it. I used the red and you either have to put a light primer colour under or more coats to achieve the brighter colours. I did a few pieces that were darker before and had to do that. Great product wish I could get it in Canada
