Tremclad/rolling paint question - flexible parts?

That thread on the Moparts forum is up to a gazillion pages, and I remember I first heard about it here so I thought I'd ask here.

I've got a Foxbody I'd like to paint, and it's a good candidate for the roller treatment. But what about the flexible parts? I know when I've painted in the past I had to add a flex-additive for the bumpers and other flexi-bits. Any of you guys done that?

Get a can of adhesion promoter from your local auto parts store.

Since my Porsche is mostly 'glass I was concerned about that as well. I did some research and found several instances where it works just fine since it is fairly thin paint and adheres quite well to properly prepared surfaces.

I shot the Locost with Rustoleum Professional in a $10 HF HVLP gun. Much easier and qucker than rolling, in my opinion.

I concur with the doc. When you spray it, you can just put it on thicker and wet sand the hell out of it (rather than after each coat).

Did my motorcycle tank that way, looks great, even resists gas (at least for as long as it takes to evaporate).

I'm not sure how Rustoleum does on flexible body parts - my Valiant doesn't have any!

Any way you can get the paint on smoothly is OK. I used the rollers - less mess, it didn't require a compressor or paint gun, and I could do it over time. The sanding wasn't all that bad.

It's good to avoid putting the Rustoleum on too thick - it takes forever to cure.

I did some experimenting with surface prep to come up with a technique to paint the stuff over bare aluminum. I later needed to use that piece of formerly "scrap" aluminum for the tunnel and I had to strip the rustoleum off. I had one hell of a time getting it off with aircraft stripper and a DA. Yeah, it should hold up to gas just fine.

Also, if you put it on right, you get a super shine and don't have to sand/polish at all.

This is all good info, thanks. I noticed that most of the cars people do this on are older, without flexible body parts. I might just have to give it a try and see what happens. I do have an extra bumper cover laying around...

My car is brand new.

Somewhere on the mopar site is a comment by someone who did it to the flexible bumper parts and had no problems. I gave up on the mopar site a couple years ago. It started going in circles and I went with my own technique.

If you go to my site: Mongrel Motorsports scroll down the page and you'll find several links to roller painting sites. I know they have discussed flexible parts. I didn't pay attention since my E30 has none. The flex agent does not assure you that the paint will be forever flexible, it just gives you some help (this is true of oem type paint). I honestly don't think you need stress over it for your Mustang. Hit anything hard enough, and ANY paint will spiderweb.

If a car was roller painted, something modern like a 90's Festiva, how do you handle the stuff like the lower valance and grill work on the front? I'm not doing this, just something I've wondered about. What do you do, get out the foam brushes and spend your life hand sanding constantly? Just rattle can those areas?

You aint spraying thicker than you get with a roller or a brush.

We rollered the BABE fox body GT, flexible rubber bumpers and all. It seemed to hold up fine.

I used a rattle can for a few areas the rollers wouldn't work well. That brings up another Rustoleum advantage: It's easy to match!

Yeah, until you do a custom mix of whatever you're rolling. That said, semigloss black works with just about everything, especially orange...
