Kit has all you require to fix a leaking fibreglass roof. Will cover a sq metre. Which is a fair size area.
You might need something (medicine syringe) to measure the catalyst.
Inadequate catalyst provided in kit. Especially if you do the repair in cooler weather.
Insufficient catalyst and generally a poor quality kit. I have bought other kits that were better. This one did not even come with a syringe or measuring cup. And insufficient catalyst provided which means you can't do any repairs in cooler weather with this kit. Would rather buy other kits on the market which may be a few pounds more but at least get the job done. Don't buy this kit.
