I have a question on priming trim pieces before dying. The piece in question is the piece that fits into the rear of the door sill plate and goes up the door jamb to the top of the interior quarter panel. It has a metal insert that grabs onto the body seam there to hold the front of the interior panel in place.

I have an Ivory interior. Most people say you should prime the part to by dyed. Most primer I have seen is black. It doesn't make sense to me to prime a white part black and then paint it white again. Is the primer really needed?

On a piece like that, I just wash it well with detergent, dry it well, then wipe it down with lacquer thinner before I spray the vinyl dye. I did a 68 Camaro interior from black to parchment using Ditzler Vinyl dye, and it turned out awesome. Be sure to use a good brand name vinyl dye.

Gene,

I hope you have an original GM part. The repros are poo-poo.

The rattle bomb dyes I used really were not too bad.

Carl,

Yes, I have my original pieces. They have discolored to a brown color on the top part right where this trim piece is most visible.

Thanks for the info.

...the wind laces. If you can, and all Im going to do with mine is glass bead them so the paint will stick. Works great.

gheatly,

Firewheel Classics here locally sells a dye that does not require a primer. I have used black and it works great. I used mineral spirits first to clean, then applied the dye.

CarlC,

Too bad the repros are junk. Mine need to be replaced badly. Maybe I can find some used.

gheatly - You really don't need primer, but an adhesion promoter. Especially on the windlace which could see some wear and tear. If you don't get a good 'bite', the dye will wear off pretty quick. The stuff I've used is clear. All you need is a very thin coat. It is made by "Bulldog" and is available at most auto parts shops (PEPBOYS). Just my opinion.
