Modern Vespa

My termoscud r154 suffered a 1" / 2.54cm on the lap portion of the skirt.
Any suggestions on what type of tape or other method I should use?
I want to stay clear of duct tape.

Could you please tell us more about this occurrance. How did this happen? What is the condition of the material? A picture would help too.

I purchased the r154 on eBay for a really good price, so I'm not certain how the tear occurred.
I believe the very clean cut might have happened when the original owner opened the packaging.
It's a very clean cut that also sliced the plastic membrane underneath the shell.

I don't think you are going to be able to get away with just using tape. You are going to need to sew a patch on. Personally, I would whip stitch the tear and then sew an actual patch over it. Like a Vespa or a Roundel patch.

I'd be in agreement here plus the added thought of sewing and sealing the underlying membrane as I think that's where the 'waterproof-ness' may be.

Depending on the denier and the nature of the rip there is a strong possibility that the raw edge of this tear will begin to fray. If you notice this, it might not be a bad idea to CAREFULLY apply heat to the edges to create a bit of a melt.

You could then stitch the opening up to keep movement to a minimum. I would then look into a more durable patch, similar to something that you would use for a tent. This is typically a combination of sealant, seam tape and a waterproof patch. I'm sure black is available.

So I just took a ride with the still ripped termoscud. It's a pretty big difference in terms of comfort it provides.
My ride is no warm! The warm radiator exhaust is now trapped under the skirt.
I'm going to take the skirt off and start on the suggested repair techniques.
I think despite the tear, still a very good deal for US$30.00 shipped!

You might want to take a spin over to the East Bay and bring it here, and see if they can fix it.

How cold is it in SF that your still using your thermoscud? I just got back from a run in Oakland and got cooked.
