Fold lines in Headliner...will these go away?

[Blakcharger440]

Hey I am installing a headliner in a 70 Charger RT and I have noticed that there wrinkles or fold lines that I can still see in the headliner from when it was boxed up.

Do I take the head liner back down and maybe iron it very carefully? I am about halfway through the install.

Will these fold lines or wrinkles go away in time?

they usually go away, unless its been folded for years....

Use a hair dryer,or use steam and they will come out or you can leave them alone and they will come out in about a week or so.If you use any kind of heat(hair dryer or steam) DO NOT hold it in one place for too long.

I purchased it from Year One about 2 weeks ago but just started installing it last weeked. I will go ahead and finish installing it this weekend.

When you are finished park the car in the sun for a day or two with the windows up on a HOT day. and your lines will slowly go away.
