Repair dented and damaged seat trim yourself

Seat trim on vintage bikes from the 60's and 70's is getting harder to find. I have bought complete used seats just for the trim which was either missing or damaged on a seat I was restoring. Sometimes it just needs polishing but more often than not, it is dented, bent or scratched. You don't always have to replace it.

For some of the popular models, you can get reproduction seat trim, but with a little time and effort, you can restore your originals. Fortunately, most are made from stainless steel so re chroming is not needed. Stainless can be polished to a chrome-like finish to look like it did when your bike was new. I'll show you step by step how I have been repairing my seat trim for years. It's not as difficult as you think.


This is a close up of the damage on the 1970 Kawasaki A1 seat trim that I am fixing. These are deep gouges that I will work on but they are a little too deep for me to make completely invisible. I am not doing a show quality restoration and just want to make the trim presentable.


STEP 1: To remove dents, you must push them out from the back. It is important to look carefully to locate the highest spots. I used a small punch and a hammer to push the dents out. Go slowly and gradually remove the high spots. Be careful not to make a sharp dent.


STEP 2: To make the surface level, I sanded the area with 220 grit sandpaper. The surface is now straight and the deep scratches are gone. As you can see the four deep gouges are still there but I didn't think I could remove them. At this point, you should remove any other scratches.


STEP 3: The next step is to use 400-600 grit wet/dry sandpaper. I used it wet. You want to gradually smooth out the marks made by the 220 grit. At this stage you will start seeing results. You must do the whole area slightly beyond the damage to blend your repair. Concentrating on one small spot can also create a low spot.


STEP 4: The final sanding is done with 800 grit wet/dry paper. Using sandpaper any finer than 800 grit by hand is not going to do much on stainless steel as it is very hard. Now you are ready for the buffing wheel.


STEP 5: Here is the trim piece installed on the seat. It was polished on a buffing wheel using the "green" compound. The entire piece was polished and although it is not perfect, the repair is barely noticeable. It was that simple.


This is the "before" picture so that you can compare it with the refinished piece in the picture below.


In this "after" picture you can see the deepest gouges were not completely removed. Polishing blends the repaired area and makes the stainless really shine.


After recovering my 1970 A1 Samurai seat and installing the restored trim, it's ready for use. Best of all, I restored the seat myself and saved money in the process.
