Default Restoring Exterior Plastic Body Panels

My westy has lot of shrinkage and stress cracks all over the black plastic body panel. I can't use a soft filler and paint over it as it would crack again.

We used panel bonding adhesive to fill the crack after it has been beveled slightly to allow more of the adhesive to fill the groove. The surface was sanded, solvent wiped and then we used polyurea to coat all the plastic body panels.

It worked great!

Wow! great job. This looks really good in the pictures. Is it as good in real life? I need to do the same treatment. Can you share the actual products you used, as I'm not familiar with what polyurea is.
The finished product looks like it has more texture. Was this part of the polyurea coating or just a visual illusion of the different pictures?

512 Westy, it actually looks better in real life. It is not as glossy.
The product is Lexis Graphyte. It is chemically similar to bed liner coating but more elastic. Traditional bed liner products have less elasticity and higher tension to handle the wear and tear. For a plastic body panel, you need something that can bridge the crack and not break with thermal expansion and contraction.

I don't have the product data on the site yet but I should have it in a couple of weeks.

My auto body shop, Auto Image in Woodstock, GA is already trained to install it and we used the westy both as a demo and training for their guys.

You will not be able to achieve the texture with Rattle Can bed liner products like the ones from Rust Oleum or Duplicolor. I'm not even sure if they will stick. This product bonds and cures in less than 10 seconds. It is sprayed similar to regular paint initially. Then you step back and hit it again for texture. The droplets partially cure on its way to the surface and that is what gives you the rough finish.

The attached picture shows the spray gun laying on the ground. It is a 2 component spray system.

I sprayed the rocker panels, plastic panels and my nudge bar. It looks really good blacked out instead of gray. I also sprayed the bumpers and the rear wheel well trim with SEM bumper coating to match. The polyurea does not work very well over those surfaces.

Looks great! Would love to see a photo of the complete van without the masking if you get a chance.

Is that a custom A/C or solar panel up there on the roof?

Very observant! No, unfortunately I have a missing AC cover so it was a fabricated replacement. I still don't know where to get one here. I may need to borrow someone's cover as a mold to make one out of fiberglass someday.

So if there are any westy owners near GA that won't mind letting me use your cover for a week, I'd appreciate it.

Groizier,

Here's a picture with the plastic all gone. Sorry it took so long.

My exterior plastic panel was replaced by Airstream in Los Angeles, 4 years ago. It recently has become "unglued", I'm clueless about how to reattach it permanently without screwing it in. Any suggestions from anyone? Right now the panel is held on by duct tape. The Westy is currently in upstate NY.

3m trim tape. Available in autozone. It has a red release liner. If you prefer adhesive, get polyurethane sealant for windshields.
