Title: Will dye affect dash?
Post by: firedome on September 07, 2011, 11:41:46 AM
Will changing the color of a padded dash affect it in any way, possibly cause it to crack, or?
Is there a best way to treat it after dyeing, or leave it alone?

Don't put it in to tight.  They need to move around to prevent cracking.  Expansion and contraction

What kind of dye are you planning on using? I've used SEM solvent based coatings and Colorplus Surflex water based coatings.

SEM uses a MEK solvent similar to gluing PVC pipe to make the vinyl soft for adhesion.

Colorplus needs the dash to be clean (use soap based cleaners first and then a wipe of lacquer thinner or MEK to prep it) and it also should be scuffed up with grey Scotchbrite pads or 320 grit sandpaper prior to brushing or spraying the coating on.
Colorplus can be brushed on and the brushmarks will go away. If you need metal parts to match the vinyl, just prime them with "The Painter's Touch" primer by Rustoleum. The metal takes on a plastic feel that the coatings stick to great.

While the water based stuff works good, I would use the Sem

I like the idea of the solvent softening it prior to dyeing, seems like
it would become part of the vinyl that way. What do you recommend Bob?

I have better results with the water base......it looks good enuff for Pebble Beach and is easy to apply

Steve's Polaraco dash worked out great....it was Mercedes olive green with a light misting of Krylon gold for metalflake, then cleared with the water based clear. Only a 8 inch crevasse down the center doomed that dashpad (lesson learned : never use a southern car dash in "negative holycrap degree" northern weather)

Bob - the finish aside, would the softening of the vinyl by the SEM help to prevent future cracking?  I've located a perfect, and very pricey, used dash pad for Sapphire, but it's black.  I'm very concerned about going thru the re-dye and installation and then having the dang thing crack on me down the road, as did the one you mentioned in Polaraco. What to do?
