Technical Anyone use a roll on primer?

Curious if anyone has used the roll on primer and what you think of it if you used it.

That sounds hokey to me, I would never try it.

 

Be better off with the $10.00 Harbor Freight gun!

 

So the paint company’s ( PPG in particular) really touted this for spot priming in the early 2000’s as a cost save to the Collison Industry. The benefits were less time spent masking and less materials utilized, and when the 6H rule came into effect with a maximum of 3 oz of material sprayed on the shop floor ( where a lot of priming is done ) some shops went for it. It works..just gotta get it flat and make sure you don’t leave an edge. I wouldn’t do a whole job that way..

 

did it, worked OK

 

I thought "hokey" is what this site is all about??

 

And what about the compressor, water trap, etc? I don't see a problem really as all it is is applying Primer. Now I feel it's not smooth enough scuff it down. I wonder if you used something a little thicker if you could reduce it a little to make it flows out a bit better?

The video was hardly about applying Primer with a roller but a pretty decent "how to" on th ewhole prep process once metal work is done. The spray guide coat is a waste of money; I use the powder on stuff.

 

I've used roll on several times... spot priming including an entire hood. Use a foam roller and feather the edges (spot priming) and allow to flash between coats. Works great as filler primer, reduce slightly to help with flow. Depending on product, blocks out just fine.

As far as being smooth enough to scuff and shoot ^^^^^^^ I don't know anyone who just "scuffs" primer and then top coats...

 

yep, this process is for priming body work or something that needs a film build followed by block sanding.
We did a lot of it when it came out years ago but I haven't used it in years.

 

Well I should have said block it out.... but my fingers were getting tired. LOL

 

Yeah I did . On my house. Worked great!! Lippy

 

The 6H rule for spraying 3oz outside a booth is kinda misleading.
It doesn't specify how many 3oz you can spray.

 

It looks like it works on that Camaro but something like my T coupe has all these ridges stamped in, external hinges to deal with and those "T" moldings along the rear window and trunk lid so I Don't think the roller would be a good idea.

The cuts down on stuff floating around in the air and going where it shouldn't isn't a bad deal and 90% of us are going to get out the blocks and long boards and sand no matter what we spray.

 

There are several cars in this thread that have rolled-on paint jobs:

Dealing with lung cancer keeps me from spraying anything. Laid another brand on thick with a roller, worked great.

Yep..line up the 3 oz PPS cups..

 

I've been using foam rollers for years. I like the Shur Line brand

 

I admit I did it. The inside of the bed on a 49 Willys truck. That was at least 6-7 years ago, it held up very well, has not been topcoated.

 

This stuff is amazing at what it'll fill. Wonderful adhesion to bare metal. I was talking about it at the paint supply store and there was a guy in there that told me he had rolled it on a car that had heavy pitting and blocked it with 80 grit, filled all of the pits, then he sprayed a couple more coats over it. Blew my mind, but hey, if it works!!

 

Thats funny, when I saw the thread title I thought "well, its been around for quite a while" then I got thinking......damn, thats like 20 years!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
