Track no use 1 la

Public roads Touge maybe.
But if you unlucky you get bigger stones, or constantly pelted by members with sticky tires, also same useless PPF will be destroyed

Depends your definition of bigger. Sepang sizes no way paint survive, unless maybe those costing 5 figure paint like Glasurite (top tier models) that generally only used on conti cars and definitely not on your usual P1 P2 T&H/Japanese
My car paint all damages until the base coat (no rust)
But some of the front roof and fender down to bare metal until rust showed. Front Bumper about half shaved until bare plastic.

This year end finally got to respray entire car from UMW Toyota Lexus Melaka, quoted 5.5k .
Long overdue pending since 2019 since very limited budget all the time

Smashing is all fun and games until that windscreen gets a bullseye or straight up crack
You'll wiser up in a hurry to either overtake quickly or stay further behind
