Filling in voids in the side panels

[wingrider]

Hello All, how would you go about filling in these holes in the side panel so the panel is smooth enough to paint?

I have heard of some melting abs into them, others using plastic weld. I do not plan on putting the side emblems back on, so need this to be smooth.

Thanks for any help!

Kitty hair, and body filler. I've done it. 20 years later still good

Yeah, I've used fiberglass and resin. Holds up well.

Thanks Guys!

JB Weld

[CYBORG]

that would be a lot of JB

I would tend to agree with Cyborg….bought some version of kitty hair to smooth these panels and rear fender out.

I did mine with JB weld and a skim of glazing putty over the top to smooth it all out.

I love JB weld. Use it for a lot of things. Always have some at the ready. But prfere it for small repairs. Always have fiberglass at the ready as well. Find it easy to work with on panel repairs. And it sets up faster

You guys may have been lucky but I wouldn't trust an epoxy or a polyester resin based filler, or any other filler that doesn't flex the same way as the original ABS plastic not to flake off eventually.

I used ABS and acetone slurry as described in the thread linked below (unfortunately, Eric's pics seem to have evaporated) to fill the void in my GL1100 side cover before painting it. It took a long time to cure but the result is ABS all the way through.'
I think if I was doing it again I would cut a piece of ABS to nearly fill the hole and glue it in place with slurry.

I also used both ABS slurry and plumber's ABS cement when I repaired the fairing for my winter bike.

Never had any issues with fiberglass. The full dragbike bodies I used were all fiberglass. The replica extended tail pieces were made of fiberglass and they also were the seat pan. You won't find much more flexing than that environment. The bike I built and painted in 1994 had a replica front fender, side covers, tail piece, and replica fuel tank that held one gallon of race gas. Still being raced today with the same paint. No cracks on any of that. I've not seen any ABS side covers flex that much to be afraid to use fiberglass.

I agree

I would flair theholes a bit to give the glass something to bit on

I don't doubt that fibreglass alone is OK for building body panels or for adding to or filling steel. My concern isn't that it won't flex but that it may not flex the same way as the ABS does. And if it isn't bonded perfectly.....

But ultimately it is up to you which way you do things.
