Anyone coat an octopus?

[paulbee]

Hi all

I've got an octopus that has a couple of chips on the corners and wondered if anyone could fill and coat with something for me please?

Cheers

Paul

I've never coated an octopus......

But I have dressed a crab

@ 'dressing a crab'

Isnt it like touching up a car - pollyfiller, a rub down and a spray coat paint?

[phtumshk]

If its black thermo plastic I could possibly fill with the black acrylic I fill my acrylic mods out with.
Just to point out it is jet black the octopuss mod looks a little on the dark grey side?

(Also Still larfin at dressed a crab quip.)

So going to go with the fill and spray technique, I've got one that's already beyond repair so will practice on that as nothing to lose!

Mmmm dressed crab 🦀

I have it on very good authority (DrunkJ AKA ThreeDJ16) that CA (super glue) is the thing, I'll quote

FYI, if you are just applying to the raw nylon, it's extremely simple just to coat the entire thing with CA without dilution. The dilution method always left things spotty and of course is worthless for a dyed version. My last several 3d prints, i just did a single layer coat (i do use the wood CA which is a longer cure time) of thin CA. Another tip is use a sponge type makeup applicator (I'm sure you have plenty...LOL). The one's I get are a black plastic stick with a oval flat sponge like tip (from Walgreen's). It's really strange, they puff up and really swell up and hold a lot of CA. The weird part is the CA does not dry on the applicator tips. Anything natural (paper, cloth, etc) is reacts badly giving off fumes and gets hots, then hardens super quick. But these sponges last through several application of an entire mod. Let the first thin coat dry and it soaks into the nylon very well. DO NOT SAND or you'll be stuck sanding any other layers and it tends to turn white (which sux if you dyed it). Naturally dry (no instant cure) and then you can apply one more thin coat and it protects very well. This is what I do for raw nylon, dye or natural. For painted, I use spray clear enamel, at least 3 layers, then apply the CA, layer by layer. Though this method requires sanding as you want a smooth glossy finish. But the CA over the nylon will give a nice satin finish if no sanding is done (and you lay down the layers even). I buy stick fast wood CA thin from Amazon. Gives you 60 secs of cure time.

CA = Cyanoacrylate

Dilution is with acetone, this is a long established method for wooden mod bodies, the discussion I took the above from was about the dilution method getting scary hot which was probably due to humidity.

Thanks VapingBad
And idea what the ratios are for the dilution?

No dilution for plastic with the Wood CA, but for wood I think it is 30-40% CA + acetone, bound to be youtube vids on it.   IIWU try and find wood CA then experiment a bit, the guy I quoted would be on my top 2 or 3 go to guys on this (machining and 3D printing) so read and reread the quote and do a few tests.  And you have to be quick applying it, prep your work area and have anything you may need in reach.

VapingBad, surely superglue is too thin to act as a filler for the deep nicks in Paul's Octopus pics.... or am I missing something?

Title is coat not fill, they made that texture on purpose.

But Paul asks about filling the corner chips????

And I didn't try and answer that, rather focusing on what I believe is the far more important and generally very poorly understood point, it's new to all of us after all.


 (I would try a heat gun for those dents btw, thermoplastic, the clues in the name)

[decoy]

if i rem right there are 2 types of thermoplastic
thermo hardening and thermal softening
i could be wrong but i dont think anybody would be silly nuff to use thermal softening stuff to make a mod as the heat from a dripper could melt it
thermo hardening hardens when heated and will not return to a soft state when heated it will only burn
only know this because you can plastic weld one type of car bumper and not the other lol

tbh if the op really want to smarten them up then the best way is prob car body filler(there are plastic ones) and then prep and spray
once the chips are filled it might be wort using so spray filler on the doors if you want to get them flat
its just like thick primer so use a few coats and it hides a lot
and scotchbrite anywhere you don't sand that you want paint to stick to

hope that helps

CA glue is available in different thicknesses.

What many know as "superglue" is normally the thin runny version of Cyanoacrylate (CA) glue. Medium and thick versions are also available see examples here . The thicker ones may be able to be used to help fill voids - perhaps using successive layers to build up the fill. But, after trying CA as a wood finish once (which some do wonderfully well and achieve stunning results with), I can say it's neither easy nor forgiving to work with - or, at least, I never found the method required to use it that way.

i think im still trying to part with some from the last time i used it lol

Oh, yeah ... I remember that part well!
