Just curious about roller painting

Many threads are posted about using garden store paint and a roller on a vehicle.

What I wonder is for a $100 more they could be using automotive paint. I assume that the automotive paint would be more durable than the wheelbarrow paint, even though it wasn't applied as per manufacturers recommendations.

Anyone have any experiance doing it this way?

Lets try and keep this thread based on facts, not emotions.

I am not advocating this technique in any way so don't flame me for asking !

Myself,I'll stick with my Iwata.

If you read my threads and posts at all you know that I will try goofy stuff like this and give it an honest look. I did try to roll on urethane clear using the best hightech foam rollers and it was a miserable failure.

The biggest problem is the air bubbles that get "whipped" into it as the roller goes across the surface. There may be some trick to using super slow reducer or some damn thing but as I saw it, it was a failure and I don't believe it can be done with any success.

Automotive paint is not formulated to be brushed on any use of a brush would be difficult at best..Saying that I have brushed a bit of primer on a sand thru when I did not want to go thru gun cleaning and all that..

The brushes used for yacht work make that iwata gun look cheap and doing fine work with a brush or roller is a whole nuther world..

Be it noted that auto refinish is oreintated to the needs of a collision shop where speed is of the essence so auto paint is made to dry or cure fast so in order to brush it one would have to do something to slow it down a lot in order to maintain what we call a wet edge that makes paint suitable for brushing..

Many years ago I bought a car that had been brush painted.
It seemed to be automotive acrylic enamel, and it looked real good for being
brushed, wtih very few brush marks, and with some sanding
and buffing would have rivaled a spray job.

I wonder if a foam brush would do a better job than either a roller or
bristle brush? Would the paint solvents attack the foam?

I think the trick is to use a very slow reducer and lots of it.....

When I was with Martin Senour we had a Marine line. It was a urethane SS and had a "Brushing converter" as part of the line. Never used it, never sold a can of it as I remember. But I wonder...hmmmmmm

I think it would need a thickener rather than a thinner which I don't think exists .. I think that's why Rustoleum can look so good ( at first ).. thicker paint, that will gloss nice, and it's very hard and goes on thick so with a cut and polish, it'll look like it's sprayed.. only downfall is.. everything else a paint should be it is not...


with my '51 Chevy, my siphon feed primer gun would not pick up the primer to spray the roof, so I got out a foam roller and rolled the epoxy on and went thru 3 rollers because it ate the glue off of the cardboard

A friend and I used a brush-on bed-liner on his '72 tow truck. The truck was abused over the years, and the bodywork necessary to get it straight enough to paint "normally" wasn't worth the effort. After sheetmetal/bondo/cheesegrater work (no sanding), we brushed it on. Couldn't even tell there was unfinished bodywork under it...brushed on bed-liner blends-in all the imperfections. Of course, it had a gritty/flat-black appearance...but it took only an afternoon of work. And it held up for years until he sold it.

yea today's oil based enamels are better i prefer the pro series rustoleum its oil based enamel has a really good shine to it and is UV protected also don't put a clear coat on this stuff the clear coat will peal off after a year nothing to stick to.but the paint will last a minimum of 5 years. but you should wax it once a year with tirtle wax.

LMFAO.


Yes, that pro series changes everything, I just hope they did not put "For professional use only" on the can , so I can qualify to buy some.
