First take a mixture of a ratio 3/4 99% Isoprophynol Alcohol and 1/4 warm water, use a facecloth and scrub area to prepare, eliminating any oils and dust that may hinder adhesion of decal.
Step 1: Lint Free Cloth
Take a lint free cloth and go over area drying and removing any solids left on washed area.
Step 2: Drying With Lint Free Cloth.
Scrub, scrub and scrub, the cleaner the surface the better the decal will adhere to the cars interior panels.
Step 3: Using a Precut Design.
The design I have is for a 1991 Plymouth Laser RS, it is precut and can be ordered this way making it easier and more cost effective, plus the company I ordered mine from gives me doubles so if I mess up I have a spare decal to fix the problem
Step 4: Decal Is On!
The tricky part with a decal is to start from one corner and slowly press the decal down onto the surface trying to keep it completly even, which is a very hard task, some kits require you to cut the pieces and join them like a puzzel, but this often leaves a spot that tends to lift up, which makes it look sloppy.
Step 5: Heres an Example.
I have cut this piece into three sections, wheres one I have adhered to the cars gauge trim.
Step 6: Next to Be Stuck.
now I need to attach the next piece here.
Step 7: Now Thats Done.
Not to bad, but the next part is the worst.
Step 8: The Worst Part!
This is the worst because there is so much to work around, you need to cut the decal a few times for places like this, but I have no photos of this annoying process.
Step 9: And Here It Is!
After 20 minutes and a lot of cutting and matching, im left with a pretty neat looking dash panel compared to the old black plastic.
Step 10: Final Photo
Heres the completed photo, doesent look to bad at all, sorry its sideways.
