By now you know I have a tendency to jump around on my prodjects, well I am painting the front fender and touching up the paint on the rear fender.
I had to pull the rear fender to mount a new tire, and felt it was a good time of the year to do some painting.
I am not going into a lot of detail on how to paint, that is a book unto itself, and there are several out there.
Just want to say painting is very satisfying and frustrating at the same time.
Especially with the urethane paints.
I learned years ago with lacquer and gradually moved over so it was a easy transformation.
You all have hear that ninety percent of painting is in the prep work.
This is very true.
The flatter, smoother the body panel the better the paint job.
The less bondo and paint, the longer the paint job will hold up.
Yea I know we all think the thicker the paint the deeper it looks, this is not true.
The shine is in how flat the top layer of the paint is, not how thick the paint is.
The thicker the paint the easer it is to scratch and the easier it is to fail, crack shrink or get moisture underneath and bubble.
So the more time you spend on the prep getting the metal or glass straight the better.
You do not want to fill your dips with paint, bondo.
When I fitted the front fender I mounted it several times, to get the look that I wanted, and I needed to cut out around the brake for it to clear.
So I ended up with two extra holes, and too much cut out for the brake.
To patch I put the fender back into the mold and added fiberglass.
Make sure you taper the fender where you are patching it to give the glass something to bond to other than a flat edge.
Here you can see the patches where the red arrows are.

After the patch is made you start sanding, first with course sandpaper 60 grit, 100 grit.
It is important that the top layer is resin and not glass cloth.
You do not want any cloth showing as this can cause the paint to fail.
So paint over it, build it up with resin then sand it smooth.
When it is perfectly smooth and flat, you prime it.
Here I am wet sanding the gel coat of the glass with 220, then 320.

I use a urethane primer filler. It is thicker than regular primer and fills small imperfections.
After it dries you can start using your body fillers if you need.
There were only several real small pits from air pockets so I used a polyester glazing instead of bondo style filler.
The polyester is much easer to sand, is a lot like thick primer.
You just don’t want it too thick.

Then you start wet sanding the primer and filler. 320 or 400 will cut pretty fast, the object is to sand out all the imperfections.
The fender was in real good shape so it only took this layer of primer and filler to get into shape.
Some times you need to do this several times to get it perfict.
You will notice that on the sides I am using a paint stirrer with sand paper wrapped around it.
Make sure you do not sand on one place too long, you can sand a groove real easy.
You want to sand the whole side evenly, going different directions.
The wood stirrer helps keep it flat.
So all I have to do is prime it again, and then start painting.

More to come latter today, the sun is up I’m going to go paint.
