One cartridge will do it for about $25.

Hi Mike!
I'm close to having to make the decision whether to use fasteners or adhesive.
How many years and hours on the RV-4 now?
Any signs of cracks, grazing or other adverse effects on the canopy?
How thick were the washers (spacers)?
I saw one post where no spacers were used -- not needed per 3M. I find that unlikely due the the expansion differential, about 1/4" over 160F (-10F to 150F).
The 3M 5200 seems a lot cheaper than Sikaflex and appears easier to apply?
