Source for Replacement Lexan for Rock Guards
Here is a link to a company that stocks the smoke Lexan. It is good to have a souce if it gets broken.

Just noticed I have a nice star crack in mine. I'm assuming the replacement is grey? Thickness? Go with the lowest tolerance? Is the original Lexan or just plexi? Looks like it installs with a spline.

Original should be Lexan. I don't have my trailer here to measure thickness, I'll try to remember to measure it next weekend, so we have a baseline thickness from the factory.

I had a talk with someone that should know, and they say the originals were plexi. If it had been Lexan, it would have increased the cost by about $200 per unit. I do know that if mine ever breaks, I will be replacing with Lexan, unless something better comes along in the meantime.

Lexan
Hey....if you have a star crack showing...its not Lexan. It won't do that.
Also, when you get the new Lexan be sure its SR (scratch Resistant). If your in the Dallas area go to ABS Plastics....I have to check that name if your interested. They will cut to size, and have many tints of color and thickness selections.

Personally, I don't think it would be wise to construct an Airstream out of transparent aluminum. I don't think the neighbors would appreciate seeing me preparing for my evening shower...

Yikes!
Here I thought the post was about rock guards and now we are making glass houses!!!! Guess you'll need the Not-so transparent version! LoL! The bronze or smoke colored would give you a nice even tan effect, Terry!

Rock Guards
As I posted earlier, I lost a rock guard to a State of Virginia Bush Hog. It threw two pieces at me. One knocked a hole in my rock guard the other cracked the battery box on the street side.
Because of the cost I decided to replace the now holy rock guard. The material was identified as Acrylic, because Lexan (Duponts trade name for polycarbonate) did not come in the dark shades like the Acrylic does, so I reinstalled the Acrylic. If some one wants to see pictures I will endeavor to produce a few.

zThat would be great, along with either a link or phone number for the source.

I replaced mine this year and the old one was 1/8" acrylic. I couldn't fine any spine material as large as the old and dryed stuff I took out so went to the local big box hardware store and found some 3/8 round grey foam in the insulation dept. worked great. Wasn't to hard of a project, I think you can find the acrylic in any larger city under industrial plastics. As a tip I was able to sell the drop on craigslist for 50% of what I paid.

Rock Guard Overhaul
I didn't realise that the spline was that hard to find. I have a Mom and Pop hardware store (Meadowbrook Hardware) close to me. I just go there first out of habit. They had it and the next size larger.

Melody- my experience follows
Um ah, from one airplane builder to another. I've seen numerous instances of star cracking on lexan windscreens installed on experimental aircraft. This is almost always caused by the builder drilling out only to the called rivet size. The correct way is to drill out to the called rivet size then give it a little more clearance. I don't have the info here with my morning coffee, you'll just have to trust me on that. Why oversize holes?- because polycarb has movement when it heats and cools, if held tight it will crack. True Story. I posted pics some time ago on another thread, try the defunct search if you need something to do. Also with google availability anyone should be able to purchase lexan, polycarbonate anywhere on the planet and have it shipped to them. Plastic supply places have it all the time, it's readily available if you know where to shop.
on edit --look at the thread "rock guard rebuild-71 Safari" pics of star cracked lexan.

absolutely correct..
Thats absolutely correct. After the first drill to size I will go one size over...plus I will use a large bit...or countersink, to bevel both ends on the drill hole. The star crack I was thinking of was from a direct blow...like a windshield type. Bullet holes don't count.
