There is a rubber "skirt" on the front bumper at all the first Fokis. It's pretty often falling off or starting to grate in the front. Most often, its fixings suffer from sutomes and kerbs. The easiest place to put a skirt in the puzzle is to use two strings and substrates. This can be done with a hammer, but the efficiency is smaller and there is a possibility of breaking the bumper or its attachments. In order not to lose a skirt, you can pin it with plastic hatchways by passing them through the bars of the air intake.
