to undercoat or not to undercoat???

If he has it professionally done it won't be glooped. It will be sprayed at about 2500 psi The stuff is tight and looks good tuff as nails. I would not use Rhino liner as that is thick. Daily driver or not, Your car is subject to the same gravel kick up as anyones. Do it now or do it later when its harder to get to . Shop around, look at other cars. Never say your not going to drive it often. You have a great looking car ,your going to drive it.
