Undercoating using Clearcoat?

[91black5spd]

Has anyone ever done this? I just got a new wrangler and I usually always undercoat vehicles I buy. I use either spray can undercoat(rubberized Marhyde) or I bring it to a place where they spray on a rubberized coating. The problem is that it looks messy in the end and I worry that rust will form underneath it where I wont see.

So, I was thinking of using spray can clearcoat and spraying the undercarriage. Has anyone done this, Any thoughts?

Back When I was living up north and had to deal with salt and snow I would prime the exposed metal underneath and paint with black rustoleum. This would mitigate the rust issues and looks really good in the wheel wells.

`How about a common sense approach if clear coat was superior to undercoating why don`t Zeabart use that instead of what they use.

I can think of several reasons why this is a bad idea.

I will be undercoating all of my vehicles very soon I do it every fall.

What are the several reasons why it is a bad idea?

Is it because it wont hold up as well as rubberized undercoat?

It will not stick to anything that is not perfectly clean that don`t sound like the underside of a daily driver.
It is not very durable it chips and scratches easy IMO this is a POOR Idea but if your mind is set on doing it go ahead you will only be out your time and 75 dollars or more for the clear coat

If I was going to use anything other than undercoating it would be spray-on bed lining that stuff is really tuff.

If you have an Auto Tire and Parts nearby, check out Penray undercoating. When done right with the straw that comes with it, it lays down 10 times smoother than anything like it that I`ve used, and is a nice satin black so there`s no need to paint it. I`ve had it last 3 years so far on my truck and it isn`t chipping away yet.

Your right it definately wont be durable. I was just thinking that it may be easier to detect problems since you can see if rust is forming under it. But since it wouldn`t work as well, rust would be more likely to form. So, I should probably just undercoat it.
Ive seen a lot of people saying that undercoating is bad on other forums because it can lead to rust underneath the undercoat. Thats why I thought of the clearcoat. In the end I think I`ll just use a good undercoat.

Also, I`ll look into that Penray stuff.

This statement is just flat out BS

Anything that seals the metal from air will prevent it from rusting.

Paint/ Undercoating/Heavy layer of grease anything that keeps air from reaching the metal will prevent rusting.

Undercoating is best because it is much more durable than other products that could be used

Some undercoating dry hard and is like paint it can chip if hit hard by a stone.

The rubberized will be thick and don`t look as nice but has the advantage of being able to not chip from a stone.

I always undercoat my vehicles myself do it every year.

What ever you use it should be reapplied every fall.

Zeabart requires that you get your car touched up every year in order to keep their 10 year no rust warranty in effect.
