under body redo

Hi all,
When i bought my Logan didn't do the under body coating. The sales person told me that its already done at factory and need not redo it. Its 4yrs old now and have done 65000km.

About 2 weeks ago i did an under body water service at a car wash. At some places found that the coating has bulged out. Checked it when the car was on raised their lift/wash platform.

Its summer time, all dry and dusty not humid or raining, now here in cochin, kerala where i reside. I would prefer to do it before the rain starts maybe by April. How often should under body coating be done.

cheers,
Zaps

when purchased did for rs 6500 in vst chenna 2009 in 06/april /2015 at 1,15,000kms did 3M under chase coating private paint 2lts rs 400/lts spraying labour rs 500 only in pondicherry

Are you sure the bulge is because of the underbody coating peeling off?
My car is 7.5 yrs old and has clocked 1Lakh+ km.

There are no issues as of now.

Get itc checked and if it needs repair, any decent service center can do it for you.
