okay, how to repair cig burns...
first thing you need is some of the material that is burned... usually remove the head liner and trim the edge that is covered by other trim piece or go to a junkyard and find something in the same or very close colour and texture and/or knap...
second...take a new sharp razor blade and "shave" the material off of the extra trim piece from the first step...keep these fibres
third...clean the burn mark making sure to remove all of the "burned" residue
next...if required in your now cleaned hole use some backing material such as duct tape or thin cotton material (think old worn t-shirt) and attach "behind" the hole.
next... place glue in the bottom of the "now clean hole" and take the fibres you shaved off in the second step and place in your hole, with lots of care you will be able to cover in the hole and the new material will make it disappear. lots of care and arrangement of the fibres with tweezers will make it look fairly good, if done well it will not be noticed by anyone who doesn't know it is there...
tips...take the headliner out. working above your head against gravity will drive you nuts...get a old headliner and burn it and fix it first before working on your irreplaceable part...
hope this helps!!!
