To undercoat or not?

[red_one]

Brand new from the dealership? Definitely NO

Now my question is, after a number of certain years, hindi na ba kailangan ulitin yun?

It depends on your driving conditions or terrains.

If you use your car in harsh environment like construction sites, off-road, muddy road, near salt water, dessert, etc. maybe it would be good to undercoat after 3-5 years.

If you use your car in normal environment, city and highway roads, optional to undercoat after 10-12 years.

This is just my opinion. It is up to you as the owner to determine when it is appropriate to do undercoat.
