Fender Flare Lines Help.

Hello all, Does anyone know what causes these tiger strips in the fender flares and how to fix them ? Thank you for any help.

 

Just a guess but it looks like someone was sloppy with a rotary polisher.

 

Could be a few things. To much release agent in mold, or batch wasn't mixed well, before injection into mold.

 

Tell folks that you paid extra for them.

 

Or that they are "Custom"

 

My truck is a 2019 and starting to show the same pattern. I didn’t mess w yet, I figured the detail guys have some manic for it.

 

Do the tiger stripes feel bumpy or smooth? If smooth how about doing a wrap?

I notice that on a lot of vehicles, not just Toyota. I think it’s the way the plastic is made.

 

it's the flow pattern of the hot plastic from the injection molding process.

only a few ways to deal with it.

1. get new flares, when they present the same pattern, repeat.

2. use a product like mothers back to black(almost all major auto wax companies have their own version as well if you're not keen on mothers products), and re-treat the flares every few weeks indefinitely.

2.5. use some shoe polish to attempt to re-dye the plastics to better hide the lines, re-treat every few weeks.

3. use a product like eastwood's plastic resurfacer for a longer lasting black finish.

4. spray paint them black with your favorite brand spray paint in matte or flat finish. i personally like rustoleum's matte finish from this product:

5. deal with it.

it's very common. this is my old ranger. the splotches on the front fender were from a lack of masking off during a buff/polish/wax job, but the tiger stripes are all natural.



before i sold it, i treated all of them with some of the back-to-black for a few weeks which returned the finish, but will fade over time.

 

Thank you all for the fast response and good info. @soundman98 _ have some of the Mothers back to black so I will give it a try,,,thnx for the idea and great info. @TA2016 Great idea about the warping,,,never though of that. Thnx

 

The one thing I like better about the Sport models are the painted fender flares. The black plastic always ends up looking bad after some years.

 

Well it doesn't fix the problem but it hides it for a while,,,,added a little bit a dressing
