Hey iMuf
Every vehicle I've had that's one of the first things I would do, is take off any pinstripes/decals & emblems if they didn't have holes through panels (made that mistake once!)
Anyway the way I would go about it is to get me some plastic razor blades, a heat gun and some gel type adhesive remover like goo gone.
Like everything else least aggressive product/way to get the job done! And on this is no different. After washing and drying I would use my heat gun on low setting and keep back 8'' or so and keep moving as to not get to hot (you just need warm enough to help loosin glue residue to help aid in releasing decal) and I would start trying to get the plastic razor blade under the edge just enough to grab with fingers and then with my heat gun would go in front of the decal/pinstrip and heat up about a couple foot or so and pull decal very slow and easy. (you don't know if the decal is stuck over a chip or a soft spot/so go easy and slow!)
After I got all my decals/pin strips removed I would use a micro fiber towel and place under the area with the glue residue still left and spray the gel goo gone over and let saturate so as not have to add any more scratches from rubbing against the surface of the paint.
On some of the older decals I would have to use the plastic razor blade to help scrub the old glue residue from surface. Check which way your using the edge of the razor blade so as not to use the dull end against the paint.
After I removed all the glue residue I would spray area down with a qiuck detail and remove with micro fiber towel and inspect surface good and under good lights to see what I was left with. Use the least aggressive cleaner you have for this as well to help in cleaning area and to check and see if you can bring the finish back to the color that was under decal.
Be careful also! I once had a 95' ford ranger splash and removed all decals and strips. started on passenger side and when I got to the drivers side cab, I found out that the strips was a bear to remove. It was to late when I finally fiqured out that it was a repaint and they clear coated over the pinstrips.
Alot of wetsanding and buffing to get everything blended in together. Hope I've help, just becareful, take your time and inspect everything closely! Take some pics and post up this will make a great how-to:dblthumb2:
I don't think you ill have to wet sand but you never know? Here's a great video of Mike showing his technique of doing a test spot on the hood wet sanding. I've been doing this for some time but I learned some great ways and better technique for wet sanding. I know it's long but that's what's great about mike's video's they show everything down to the finish.
