V50 Guzzi re-paint ie: Therapy

[nvr2old]

Thanks, Bill. I'll try your suggestion...tick tock, tick tock..30 minutes later..

I got to the shop yesterday to start work on the plastic parts for the V50 Guzzi and the GS fairing. Both have numerous cracks and breaks. The GS fairing must've been dropped on the right side. The lower mount is cracked all the way through and the upper corner is broken off but a very clean break. The part fits together perfectly.





My 2 go to tools.







V groove the cracks..



Fill with 2-part epoxy..



Let dry and sand.. Missed filling one tiny spot, I'll pick that up when I do the inside.

The Guzzi fairing was pretty ugly. The worst areas are where the turn signals mount. This was a bad fix from the past.



V-grooved the cracks and removed most of what was used to repair



This side wasn't nearly as gross.



There was also this lovely repair between the fork openings..





Ground and filled..



The fairing has been repainted at least once with who knows what kind of materials, so I just sanded it off. It was also skim-coated with plastic filler for some reason, but when I removed it all, it looks just fine..hmm.

The tail section was also cracked in one place.





It, too, was V'd, sanded, filled and finished.

I spent a lot of time sanding the front fender and fairing's trailing edges to get them perfect again. No pictures will show that until some primer is sprayed on. Next week I'll repair the insides of everything then on to primers. Thanks for looking, and thanks again, Bill for the tip on a sharing site.

Nice work Larry, the repairs look good!

I've had good success with Flickr myself so far, and a while back they advised they were capping the free usage at 1000 photos which I'm now very close to. They only want $US40 per year last I checked (unlike Photophucket's no notice $US400 ransom note) so I figure later this year I'll pay up to keep it going. I think they went about it the right way at least... anyway, let's not let me distract us from your work here, glad you found somewhere to host your photos

I really liked flickr, too, Pete. It was easy and always there for me, also. I noticed in their Help Section a LOT of people complaining about not being able to upload pics. I futzed around with it for almost 2 hrs. yesterday afternoon to no avail. It was extremely maddening. I don't have anywhere near 1000 pics in there, but I'll keep my options open with it. Imgur was a breeze to use and worked flawlessly for these posts.

Ah ok, not had any issues myself, I use the app on my phone to upload. It's a little annoying at the moment though as it keeps telling me I'm nearing my limit and it does seem to post "ghost" images which I need to clean up via the organiser, but it hasn't bothered me too much just yet.

Interesting your way of using epoxy. You glued the fairing together like broken crockery!
I've been including a layer of fiberglass cloth on the hidden side of fairing breaks, for additional strength.
My GS side covers, and CBR600F1 body panels feel like polystyrene, both 1980s bikes.
My CBR600 has large crash damaged lower panels that were repaired with fiberglass cloth and epoxy.
My GSX750F body panels feel more flexible, almost like vinyl, 90s bikes.
I've repaired their side breaks/cracks with epoxy and fiberglass cloth.

To me, that's the beauty of the 2-part epoxy..it's virtually the same material as the plastic parts. It's really strong and yet flexes at the same rate as the part it's being applied to, whereas fiberglass is rigid. If you try to flex fiberglass more then just a little bit, it cracks..like..glass. Fiberglass for fiberglass, plastic for plastic parts. I also do the same to the inside of the parts. I've even made mounting tabs for broken side covers from epoxy and it works great. When finished, you can't even tell there was ever a repair made.

What epoxy do you use? I v-grooved some cracks in my 850 side covers and filled with a plastic epoxy. It didn't hold.

I repaired some major damage to my side covers, and even fabricobbled an entire missing section using two part plastic epoxy. I used Loctite brand plastic bonding epoxy, but I've used Permatex plastic weld in the past to good effect as well. If the crack is pretty big, I will usually skim some extra epoxy on the back of the crack as extra re-inforcement. I've heard of people using fiberglass + epoxy for reinforcement and also seen tin tape too.

Strange. If you used a 2-part epoxy specifically for plastic, it should work really well. Especially with the 5-10 min. drying time. I go to any Ace Hardware-type store and it's available for 5-6 dollars for the side by side syringes. Prep is important to having it work, too. Clean, clean, clean, and sanded really well all around the repair area. I also go to the other side, V the crack out there, too, apply, sand, and done. That repair I did to the GS fairing is as strong as it was before the break. Love epoxy.

Got to the shop today with the intention of repairing the back side of the parts. I like JB Weld, but not for plastic. It doesn't hold for some reason.





Ground down the areas and V-grooved the breaks.





This is the 2-part epoxy I'm using. it stays where you put it and doesn't run or sag.



After sanding it came out nice. A solid repair on both sides now.





Skim coat of filler.





The GS fairing is ready to be sanded and prepped for primer. On to the Guzzi fairing which is rough. The one turn signal mount needed have all the old crusty repair removed..argh. Big hole left.

[nvr2old]

I put masking tape down as a barrier on the inside, and then gooed on the epoxy on the outside.



Then filled the back



Spent a lot of time filling and sanding the back side..what a pain..





It took forever to sand the front sides with only a skim coat of filler. Tiny little spaces to get your fingers in, but persistence pays off.





Hard to tell in the pics, but all's well that ends well. The Guzzi fairing is ready for primer, too. The front fender needs to be sanded as do the side covers, but those are a breeze.

Wow! Outstanding work on those repairs!

I'll be buying some of that Plastic Welder epoxy ASAP!
