johnkor, stop misleading. PU cannot be repaired if it's broken.

u think aluminium is cheaper or PU or fiber ah?? compare with this 3 material, which one can be easy to custom made and also cheaper?? also which is lighter ah?

ur cracks meaning under the hot sun for a long time, it will just crack or what?? i noob at this kind of stuff. but i wanna do some custom fendar to make my car more light.

what about fiber glass?

fiber n fiber glass the same ah??

but which is more better to make car fender?? aluminium or PU or fiber wor??

If i not mistaken, i heard that Fiber can mix with PU right?? So it will be hard a bit yet a bit more impact resistant huh?? Any idea how much will it cost to make a fender using aluminum also where to find those ppl to make it huh??

Cracked because of the heat of the sun AND the engine. If your bodykit is white, it will look damn ugly because it will turn yellowish and when see from near, those "yellow veins" can be seen easily. At this stage, the bodykit will become like kueh-ka-pek liao. Not to mention fiberglass is carcinogenic. 

If you're not changing bodykits every single month, I suggest you take other alternatives suggested by others such as aluminium and if you can afford it: Carbon fiber.

around sunway area got custom bodykit shop rite?? Any recommendations?

Which area are you from?? KL or PJ?? Both works well for me..

dunno wat is carcinogenic means ma..so if i wanna make a fiberglass fender, i got to take out my current fender to let them do the carcinogenic thingy?? what if i wan to extend the fender out a little bit?? wider fender..

who AFAIK?? i saw this everywhere..

I don't really like to ask shop question..cause 1st, they are busy..2nd they only do what you ask them to do but if there is any pro or cons, they won't tell you..3rd if i ask already, but the price they charge me very expensive, it's kind of wasting their time on me only..

So better ask ppl over here..better lor..
