Last weekend I made it up to the shop and got a little work done. I spent most of my time getting a new shop compressor installed so ill have a steady supply of air at the shop and at home now. Be a huge help with getting this thing finished.
We got the passenger side firewall finished up until body work.
We also got my down pipe done. The exhaust will be all 3.5" back to a 5" adapter that'll run to the stack. I was going to use 4" but the parts truck had 3.5" and it ran really good so it should work and give me some breathing room to run it under the truck. It's all tacked together from the turbo to under the cab now. Luckily when we put a new 5" system on my little brothers powerstroke we saved his stock exhaust and it was all 3.5" so I have all of the bends and tubing I need from that old system.
Last night was my first night back at school so I could work on the bed. I got started on the Dually fenders last night.
I've had a lot of you guys message me asking me to document how I repair the fenders so ill post it as I go and try to explain the best I can now we do it.
First I gathered up all of the broken pieces I could find. I got the edges of the outer side cleaned up and ground down about 2" on each side of the breaks. I used a air die grinder with a 36 grit wheel on it but use whatever you have around. Just be super careful not to get to crazy or you'll get it to thin and make more problems. All I did was ground into the gel coat and tried to expose the actual fibers for the new resin to saturate in.
This is the right front of the fender. It's the worst area. It actually has a huge piece broken out of it.
We also did some minor repair on the back of the right fender but I didn't get any pictures of that. It was just a really long split.
This is the other bad area. It's obviously the back of the left fender. I got it ground down and fit back together to the point I was happy that it wouldn't be to hard to to finish the body work on it.
After I got it all together I cut some matting up into strips and layer it on. Just mix up some resin in a mixing cup and brush it into the exposed fibers glass and gel coat. Try to stay off of the paint because it won't adhere to well and will eventually come off. Once the fender has a bit of resin on it lay the matting strips on one at a time and brush them down with resin and a paint brush. Try to over lap the ends and use a couple stacks of matting on them. I used a heat gun to dry it so if your impatient like me heat will speed the dry time up.
This is basically just a band aid. Tonight ill pull the fenders off and they'll retain their shape now that everything is structurally sound again. It's already strong enough I can grab the broke piece and ya k on them and their not going anywhere. Basically ill build all of my strength into the inside of the fender.
I almost forgot to mention that a fiberglass roller is VERY important in doing this stuff. Once you've layer down the matting and its resin soaked just gently roll the area with a roller and it'll get all of the air out of it and the one I use has spikes all over it so it leaves a rough texture for another lay the have some adhesion. I also have a grooved one my little brother made for me for doing the last layer. It leaves a nice smooth surface to start doing your body work on.
This is the roller we made. Used 1.5" billet stock about 2" long is all you'll need.
I hope this helps someone out there wanting to do fiberglass repair on their own. It sure beats spending the cash for a new set of fenders. Ill keep updating this as I go on them.
Sorry for any typos in advance. I posted all of this from my phone lol.
