A few questions about spraying Al's liner (1 Viewer)

[Sparky34]

Because of the climate here and salty roads in the winter, my HDJ80 is showing a lot of rust on different places on the car. Since already more than a year I'm searching for a solution to stop this process, and after getting some different prices at a paint shop I decided that I want to respray the complete car with Al's liner.

I don't use the 80 for exteme offroading, but it's also not my daily driver. The car is used mostly for overland trips. I was looking for an option to repaint it in a different color, but with a paint which is more tough and durable as the "standard" car paint. In the end I'll be driving mostly offroad with the car, and I don't want to cry for the first or second scratch.

The car will be repainted at a professional paint shop, this is because I don't have the space and the time to do it myself. But the paint shop never worked with any bedliner before. I read all liner related topics here on the forum and on other websites, but I still have a few questions:

1. After sanding the car, is it needed to apply first a primer?
In the Al's liner kit there is a primer, is this enough? The paint shop itself says that there needs to be first two layers of a good quality primer and then the Al's primer and the paint, is this correct? In what way do I get the best and most long lasting result?

2. With what air pressure do I get the most smooth finish?
The Al's liner manual says the air pressure needs to be as low as possible (35psi), but here on the forum I read that most people spray with 100PSI. Also is it better to apply with more trigger or less trigger?

3. Can the Al's liner also be sprayed inside the doors?
Or is it to thick so the door won't close properly anymore?

I tried to send an email to Al's for some help, but they are not answering my email. I hope that one of you can help me.

I used Raptor liner and did not prime. I just scuffed with scotchbrite pads, cleaned it thoroughly and then shot the liner at 55 PSI. I like the texture I got. It went on pretty thin and it took two coats to get it where I wanted.

Thanks for your reply.

I did it this way a few years ago with another car, I used the scrotchbrite pads and rolled it with army green paint. But after two years the rust came again from under the paint. For the Landcruiser I hope for a better, longer lasting result.

Is it possible to use a primer under the paint? And is it better this way?

Just watch the Al's liner video on their site. If you lightly scuff the surface and spray on the "adhesion promoter" first, you won't have any problems. The chance of rust coming through the liner is slim to none. As far as texture, I think trigger pull has more of an effect than psi. It'll take you about 30 seconds of playing with the trigger to figure it out. As for the doors, I would say yes, you could still close them if you sprayed the jambs.
