A few years ago I got a 2-person tent for backpacking. At some point, I let the rain fly get too hot. It became sticky and its waterproof coating peeled.
I tried to buy a replacement rain fly, but apparently the manufacturer has discontinued the tent model and no longer sells its parts.
This seems unreasonable to me. I want to buy a tent knowing that if I damage it beyond repair, I'll be able to buy replacement parts. I don't think that tent technology changes too fast to allow this.
Does any tent manufacturer promise to sell replacement parts for some predefined period of time?
Clarification
I'm not asking about warrantees, in case of product deficiencies. I'm concerned with those times when the damage is clearly my fault. I don't expect the manufacturer to pay for my mistakes.
