For skirting,i will go for Fiber instead of PU..
Bcoz before this when i want to buy a skirting for my car,i had asked several people,n most of them prefer PU..
but after bought the PU,maybe i'm not so lucky,my car lip start to show distortion that cause of hot climate..so now i planning to change it with fiber one..
another experience is my sister's car had been hit n her car sideskirt had cracked..but after repaired,it look like nothing happen..
For me,the only advantage of PU is it flexibility..

PU = plastic
Fiber = normal fiber
FRP = fiber reinforced plastic means mixture of plastic and fiber

Ranking of durability:
PU > FRP > fiber

Ranking of ability of repair:
Fiber > FRP (I didn't include PU because PU can't be repaired)

what's the difference between PP and PU?

can i ask ABS or fiber is heavier?

ill b getting a spoiler soon ... one shop has fiber ... the other has ABS

i want the lighter one

I have same question as above, which one is lighter? and what is the price like?

actualy FRP and fiberglass can be same material lor
glass fiber cant stand alone unless being reinforce by plastic matrix so call fiber (fiberglass) reinforced plastic or FRP
normally they use the combination of glass fiber for fiber and epoxy for plastic in FRP
in industry fiberglass is 'bahasa pasar' for FRP

If $$ is not a problem, go for PU.
U will probably scratch it somehow, and fiber will crack easily, cuz it's less flexible.

So guys how to differentiate the physical looks between a PU material and ori body kits which uses PP material? I send my wira for a change of SE body kits so when i go to check em i would like to be sure....

Hi need to bring this old post up because I have question to ask. Recently I sent my car to install bodykit. The the front and rear under spoiler looks ok and acceptable. The trunk spoiler have a little bit uneven but I do not mind it and it still acceptable. However, come to the side under spoiler, the surface looks so uneven. If there only have little bit uneven then I still acceptable but mine is too many uneven surfaces.

The modulo bodykit for Honda City.


Ask the accessories shop’s boss, she says that the bodykit is made by PP material, it is normal. However, last time my old car bodykit never have facing such kind of bodykit with so many uneven surfaces. Even my Vios original bodykit are so smooth and flat on all their bodykit surfaces.

May I know is this normal? PP or PU material really have this kind of problem?

Are you sure you are installing "Modulo Bodykit" and not "Modulo Style Bodykit" which is imitation?

Any plastic injection mold are subject to shrinkage after the molding. High injection pressure machine, precise mold and control of even shrinkage is expensive.

That's why LEGO, action figures, Bandai model kits are so expensive.

When comes to bodykit
- Top quality = direct surface sanding and painting.
- Ok quality = touch up, including surface touch up with resin exactly like the yellow/brown clay resin after accident, sanding then only paint. Yours falls around there, a lot of Taiwan 3rd party accessories are in this quality level. Maybe they didn't touch up and straight paint.
- Bad quality = At lot of repair, and high variation between batch. Customer A ok, then customer B fitting problem. Need to cut and retrofit for some case. Some warp not straight. The mold also not accurate, the sharp lines are blur.

These are the molding quality, and not related to the parts durability.
Some shop don't know lazy or no experience, didn't sand and straight paint base coat. Even good part the paint adhesion is not good, will peel off after a few years.
Good workmanship shop will sand, then paint adhesion promoter primer, then only base code, and other layers.

From my situation above, the bodykits are now being coated and if I send to workshop to fix the two side under spoilers on left and right with putty filler then resanding and repainting. I have to wait for another 2 weeks to a month time until the painting are fully dried then I only can send back my car to re-do coating again on the two side under spoilers.

I think the material for your bodykit most likely made from PU. PP is much better but of cos more expensive.

Depends on the paint, my detailer use Glasurit paint, with medium speed hardener on clear coat. He always recommend 2 months before coating or PPF also by him.

Side skirts, diffuser are prone to abuse, after 2-3 months of daily driving the surface will be rough on touch. Depends if you want perfection on the parts that destined for abrasion loh.

Update from my previous post. I was ordered another set of side skirts from Honda Malaysia. This time is directly installed the genuine Modulo side skirts. Yesterday I was sent my car to Honda service center to replace the side skirts. Now it looks more solid and smoothness surface.
