Well, the answer to your question is essentially this: Sort of.
Sierra Designs Nomad 4.2 Tent
Sierra Designs Nomad 4.2One the one hand, it is possible to patch a tent聮s waterproof polyurethane coating, or even re-coat the entire tent. Kenyon makes a product called Recoat 3 ($8 for a tin that covers 75 square feet; www.campmor.com) specifically designed for that purpose. You聮d probably need four or five jars of the stuff. I聮d dump it all into one small bucket and use a good-quality, three-inch paint brush to apply it, rather than the little applicator that is supplied.
I have not used the stuff so cannot attest to how well it works, particularly when completely re-coating an entire tent. And you聮ll surely end up with thin spots (or thick spots) versus the even factory applied coating.
But the larger issue is this: I think your tent is toast. The fabric may look fine, but it obviously has suffered from heat, humidity, and airlessness. My belief is that in a strong wind storm the whole thing could just fall to pieces.
So my best advice really is to bid the Lafuma farewell and invest in a new tent. Sierra Designs聮 Nomad 4.2 (on sale for $220; www.rei.com) would do nicely. As for storage, you聮ll need to use a mesh stuff sack, preferably one for the fly and one for the canopy, and keep the tent as dry as possible in humid Singapore.
