Fixing cracks in fireblade plastic

[Honda434]

I had a bike damaged being shipped so I had to fix and repaint some pieces on it. If anyone is interested this is the process I use.

Was that an aftermarket fairing in ABS plastic? How would you deal with fibreglass? I mean would you use plastic welding rods on cracked fibreglass, and if so, what type?

When I refurbished my ZX6R I bought two or three used fairing lower side panels via eBay which all turned out to be tattier than hoped (though they had all lugs intact). In the end I got NOS but it was expensive. I kept those tatty fibreglass panels and intended to have a go at fixing the cracks and deep scratches, then sell them. However, I’m not sure I have the skills, and they’re covered with OE decals which I’d like to keep or replace cheaply.

It was oem plastic. Fiberglass has to be ground and new fiberglass Matt laid out. If it’s real minor you could possibly you a two part Panel bond.

You repair fibreglass with more fibreglass, and possibly flowcoat/gelcoat depending on how damaged it is.

If you want to see experts on fibreglass repair, go on a kayaking forum. They knock dirty great holes in boats then patch them up again.

Fibreglass cloth is usually a stronger repair than mat.

If you want to just stick broken fibreglass parts back together, look no further than West Systems G-flex. You'd literally be able the hang the bike off it.
