how to use polyurathane

ok guy's what's best to use fiberglass or polyurathane and how do you use them both i would like to have someone tell me how to use polyurathane in detail with pics

Okay, what are you talking about "how to use Urethane?" Are you taking about trying to make your own kit? You can make your own fiberglass kit, but you can't make your own Urethane kit. You can mold fiberglass, work with it to make it fit better if you get a kit with bad fit. You can't do this with Urethane, what you get is what you get. If it doesn't fit well, tough luck. That's why it is ever so important to buy a qaulity Urethane kit. Now, Urethane is more durable than fiberglass. Bumping a curve etc...can easily crack fiberglass (it can be repaired though, you'll need knowlegde of glassin). Urethane is considered "unbreakable" becuase it if very durable. It's the same material OEM uses basically. SO bumping a curve may scratch the paint, but the bumper won't break like with fiberglass if something hits it. As for "how do I use them both?" YOu can't make your own Urethan kit, you can't mold it. You get it, drill the holes for proper fit, and bolt it on bascially. Fiberglass usually needs to be molded, etc, to make it fit prefectly (you can mold fiberglass). But as far as "how to use them," you don't really "use" urethane like you'd use fiberglass. Both have benifits and downfalls. Fiberglass is easy to work with and relitivly easy to repair. However, it is very fragile and can break or crack easily. In that sense, it's not the greatest choice for daily driving for some people. Urethane can be a butt to paint if you don't know how. If can't be molded, like fiberglass. So if the mold was bad and the kit doesn't fit well. you are stuck with it. However, it is VERY durable and hardly ever breaks (like an OEM bumper). What is best really depends on your wants and needs. I can't tell you that. Only you know that.

Just backing up fiberglass :D

Good quality fiberglass kits are extremely durable and can withstand an inane amount of abuse and still be fine. My fiberglass kit has withstood 2 car accidents, and an over drift into a curb. I still have the same kit and still looks new. Its been around 6 years of abuse.

Yes, true...qaulity fiberglass will last a while. Most people, however, don't buy qaulity. They look for cheap price. They buy an inexpensive knock-off, and it doesn't last as long. If he goes fiberglass, get a qaulity brand. You get what you pay for.

You get what you pay for... couldnt have said it better

You know though, it amazes me how many people fail to grasp this simple concept, lol.

So how much should one expect to pay for a quality kit?

or where can I get quality kits?

I was told importfan.com has really good kits and they are blue class...true?

"Blue class" is a gimck most of the time. It has nothing to do with how well the fiberglass was laid by hand orwhether it came out of a chopper gun. It is a "gel" coat laid over the fiberglass. I have seen kits before where the underneath fiberglass has air pockets, etc. These don't show through the blue gel coat...as a result? Air pockets burst, creating diviots in your lovly paint. Another thing I have seen, abit rare, is a bad gel coat, where paint doesn't even adhear, they had to sand through the whole thing. "Blue Class" essitanlly preps the kit for painting...a lazy person can do minimal prep and shoot over it, and it will stick better than otherwise (not recommended). A qaulity kit, like Bomex, ground designs, to name a few, don't "blue class" there kits. These kits are higher qaulity too, these are what the "knock offs" like bodykits.org, importfan, and extreme dimensions knock their designs off of. These are where you see "blue class," with the knock-offs. "Blue class" is just a gimick created by the companies that make knock-offs. It gives the "illusion" it is higher qaulity. Forget getting a kit because it's "blue class." Get a good, qaulity brand of kit. Remember, just because it's "blue class" doesn't make it a qaulity kit, it just looks cleaner. Qaulity depends a lot on manufactorering techinques (hand-laid or chopper gun), how well it's hand laid (if it is), how well the model was constructed, qaulity of the fiberglass used, etc. "Blue class" is a gel coat put over all of this, it covers and hides much of this. In truth, it just makes it a little easier to paint in theory. As I said, I know of plenty of cases where it's not true. Also, the cheap kits NEVER FIT CORRECT!!! You end up paying more in the end to make it fit correctly than you would have buying the more expensive qaulity brand in the first place.
