Thanks for all the info...
No problem. Got a chance to test it out on a ride with 12 other rigs on both wet and dusty trails that were rocky and through some bushy areas too. It was a good test of the screen for sure. Overall, I am pretty pleased with the results.
Pros:
We left it on when we towed it down the freeway to the trail head. Sat dead steady even at 75mph so the Velcro holds very, very well.
Visibility was great all day long. Most of the other cars had glass or lexan windshields or 1/2 windshields and they had to keep cleaning them with a rag and/or water every time we stopped. You could see the glare and scratches on the folks with lexan screens.
Great airflow - While I can't comment on how airflow was for them, I could easily see how it would get hot and stuffy in the cabin and I really appreciated the airflow the screen provided.
Good protection from mud/debris - The screen material held up well to the bushes and debris that was tossed up. It kept the thicker, clumped mud out of the cabin, at least any that was flying in from the front. However, the mud and water coming off the tires still made it in. Wife if thinking about making some screens for the side that hang off the top of the cage so we will see how that plan comes together.
Mediocre:
It didn't do much to keep splashes of water out. It might have helped a tiny bit but not much
It was OK but not great and keeping dust out. It did cut it down some but with the sides wide open anyway, we were still fighting the dust to some degree. Goggles or visor will help with that.
Cons:
Obviously not a solution for winter riding. However for summer riding, I think this is a great solution.
Dust - Maybe the lexan and glass windshields do more to cut down dust, I don't know. I wish it would do a better job of eliminating the dust.
Weave - Superscreen has a tigher weave material that might do a better job with dust but it would also restrict airflow a little more.
At the end of the day though, I think the first test was successful.
As for materials. The screen material from home depot did hold up well. However, I got a sample of the Superscreen I linked above and it was noticeably stronger. Should make another one, I will absolutely use the Superscreen stuff. I can see how the Home Depot stuff could tear, I didn't get that feeling from the Superscreen stuff. However, the Home Depot material did have better visibility...it's not that the superscreen was bad, just that the Home Depot stuff was better in the visibility category.
So, there you have it...for $50ish dollars and a day or so making the screen, I think it is worth the time and money.
