Once upon a time.

Now, it seems to be primarily political drivel and some guy with a stream-of-consciousness style mixed with conspiracy theory and NASA hatred.

Those were the commercials.

Back in 1959 they took the monkey over him, and he's never gotten over it.

You imagined it.

Tech posts are punished by long rants to follow.

Not to be disrespectful but I just ignore it. There are also filters I haven't figured out how to use yet. There are still bits of good information that comes through but I wished folks wouldn't answer some of the obvious drivel that gets listed here. If no one commented on the stuff, perhaps less would get posted.

Yeah,

I remember the fellow who posted a suggestion on getting good paint adhesion. He stated that when you get to the last primer coat, to just use a fine distant mist so you get a bit of a "gritty" surface. His contention was this gave the color coats some bite to stick to the model better. I've used it and he is right. People were calling him a stupid bastard. You have to sand the primer and he came back with essentially read my note. "When you get to the last coat, sputter it on. You can sand all the other coats you want to." I know as before I did this, I would use ultra fine sandpaper on the primer and paint would flake off with little trauma. It's ashame people get spastic over technical issues as I think more folks would post helpful tidbits if things weren't so bad.

I ignore most of it, as well. It's just unfortunate that there's so much of it; there used to be a lot more quality content.

I don't recall anyone being called a "stupid bastard" in a paint thread, but with a penchant for hyperbole being the norm on RMR...

A rough primer finish will give you a rough paint finish. That's it. Paint is a magnifying glass, not a coverup.

I guess it depends on one's definition of acceptable finish.

If you can see flaws after the first second of flight the finish sucks.

If an auto body shop (or other "professional") painted it, the finish sucks.

If you claim the finish is perfect and I see a flaw, it sucks - unless you change your mind about it being perfect.

I had a rocket at a launch and people were exclaiming how great the finish was.

I was disappointed in all the mistakes in it at the time.

The first person I showed all the mistakes tosaid , "so ? it still looks good."

after about the third person saying how good it looked,

I quite thinking it sucked myself and now I like how it looks.

a finish might just be part perception and part attitude !

Eye of the beholder... ; )

Hey Jerry started it..(:-) Why did you bring it up, hasn't it been quiet lately?? :)

Then it looks good to me. ; )

Hey, I do good to get primer on.

Sanding? We don't need no stinking sanding!!!

Randy

Hi Tweak,

No, I believe the words were stronger and you are wrong. As long as the mist/particle size is small enough, a few coats of color will fill in the valleys and the finish will be smooth. If done right you can only feel the roughness with your hand not really see it. I was always wrong sanding to ultra-fine finish of the primer before shooting the color. Of course if you really want "glass", wet sand the color coat and shoot several coats of lacquer. It is extremely tedious but boy does the car wax make it look nice. I've also found the one can get away with a cheaper color coat if they are going to invest the time in wet sanding and shooting lacquer. Been lucky sometimes in shooting a good quality of color that it looks so good, I don't bother with the lacquer. Yes I do like to fly sometime! :)

Hey Randy,

Sometimes after shooting primer, I see where there may be a fine defect in the grain that can be remedied with a sand job and extra coat of primer. Plastic nosecones sometimes show the putty underneath with one coat and a second makes it more opaque.

Kurt Savegnago

Wrong? Believe what you will. If you have to wet sand the color coat for anything more than the adhesive requirements for clear, then the surface prep was inadequate. Wet the primered surface with water before you paint the basecoat and that will give you a good indication of what it will look like when sprayed.

Now, if you want to have a little contest...

If you shoot automotive primer like I do, try and find a brand/formulation that has the highest solids content. They do vary. Heavier solids primer is a bit more difficult to spray (sputters easily), but you'll find that if fills defects much more quickly in fewer coats. Solids content, usually expressed as a percentage, should be listed on the label somewhere. Oh yeah, it'll cost ya more too, but it's way worth it...
