Let's Talk About Painting the LOC 4' Goblin
A 4 foot diameter Goblin? That is going to take a LOT of paint!
Let's Talk About Painting the LOC 4' Goblin
Certain rockets look good with different fin edges. The Goblin and Der Red Max look best with squared fins, they're not designed for altitude competitions.I would never build a rocket without at least rounding the leading and trailing edges. Leaving them square just looks like heck to me, like someone couldn't even be bothered. If you're not going to round them, maybe don't even bother painting at all because it's a disposable rocket. Tips should be left square, as it's generally aerodynamically more efficient.

I have found a significant difference in brightness of lighter (red and orange) top coats when going over white vs. grey primer. Yellow will be even more so. I use the AQ white primer under most any color coat.
I've used Rusto filler-primer, but don't like how it sands. @hcmbanjo has repeatedly posted his finishing techniques and uses Dupli-Color FP101 filler-primer, available online and at auto parts stores. Says it sands much better. My next build will use it.
Asterisk to all that is, I like the Rusto Golden Sunset color on the Goblin, and will be using it on the ones I build (different sizes). I've sworn off Rusto, except for that color. It's an enamel, so the AQ black likely won't play nice with it. I have a can of Ace brand gloss black to go with the GS. I should try the Ace white primer, too, since it's considerably cheaper and easier to get than the AQ white primer.

Ok ok it was a typo lol. Although that would be awesome.A 4 foot diameter Goblin? That is going to take a LOT of paint!

Thank you, I will try this next time.Instead of "adhesion promotor" I hit my cone with a propane torch like someone suggested in a prior post. It was scary but I did it and the filler primer stuck like a charm so I'm not disappointed.
And there's some very good science behind this. I read about it once, but can't honestly repeat it accurately, so I'll just say, "Yep! It works and it's supposed to, because, SCIENCE."

I learned about it originally when making a SPAD: Simple Plastic Airplane Design. You made the wings out of corrugated plastic with the spars made out of wooden yardsticks. In order to get the plastic to adhere to anything, you had to hit it with a propane torch. Not enough to melt, but just pass over the plastic where you want the CA or epoxy to stick.
And that is exactly what the adhesion promoter does. It softens the plastic.Instead of "adhesion promotor" I hit my cone with a propane torch like someone suggested in a prior post. It was scary but I did it and the filler primer stuck like a charm so I'm not disappointed.
Propane torch was free though lol.And that is exactly what the adhesion promoter does. It softens the plastic.
YES my parachute is flourescent. And I considered the color but decided to stick with my chosen theme. I think all will be okay. And yes Wrightme43, I am using the Kustom Canz though I'm worried it will compete with the color I've chosen. I'm uncertain if that stuff sprays out clear or a shade of blue all its own. I'll find out next week!With that being the same color as the sky, I hope you have a fluorescent orange parachute
I think he is going glow in the dark blue from Kustom Canz.
No worries.If I understand correctly it is clear, and best used over white basecoat. It shows blue glow, in the dark.
It should work over blue too.
Also my apologies @Stargeezer,
I didn't pay attention to detail.
The Kustom Cans coat is laid down first, the clear coat goes on top of the colorNo worries.
You think I should spray the Kustom Canz under or over the clearcoat?
I've not had any problems either. I might sand with 320 grit and then spray, or I might prime and then spray. I have an old rocket that I sprayed color directly on the nose cone and body tube without primer. Over time some paint has come off of the body tube but not the nose cone.In all my years of building I only had one nose cone adhesion issue (a Dynastar kit). All I ever did was wet sand the nosecone in the kitchen sink with 400 grit paper, dry it and use my normal Dupli-color Sandable Primer--same as I use on the airframe.
