Simply SP-037 Spray Putty 400ml – Fast Drying – Great Adhesion – Corrosion Preventive – Multiple Application, Aluminium

I bought this to fill the gaps and hide the worst of the layer lines in 3D prints. Well, this stuff is amazing! It does this perfectly. It dries really quickly, so you can apply, sand and re-apply quickly. I completed a model in an hour this morning and gave it 3 good coats.I also really love the colour. My most recent project was a copy of the head of the horse of Selene (in the picture) This needed a lot of filling and several coats of this spray as well as lots of sanding. I think this colour really looks like stone when it is dry. It dries really matt. For this model, I then waxed it with some beeswax to make it look weathered/older. It also really accepts paint well when dry.There's loads in a can and with 2 cans I've done 4 largeish 3D prints.I highly recommend this stuff!

This stuff is incredible. I can't believe I'm only finding this now. I've used 3 cans re doing all my props. This hides layer lines so effectively. So much better than filler primer, even high build stuff. Reading more into this its actually an acrylic resin in a can. Drys fast, can be sanded to a mirror finish for paint (but not really needed). Great stuff! Ordering more as we speak. 2 Coats of this will hide layer lines from a raw 3d print.(A little sanding is needed for really bad lines)

For £3.75 a tin this was the best value spray putty I have used. Great on 3D printed PLA, a good thick layer, leave to harden for 24 hours and sand off in water with 400 grit wet and dry and the model will go glass smooth. You may need to repeat depending on how much of the layer lines you can remove before application.Sadly, for some reason the price nearly tripled to £9.03. Not sure if the vendor thought they would exploit the customer, but I will not be buying it again until the price drops to something nearer the original, lets say £3.99 to be fair.No longer value for money, trying MOTIP now.

I've bought many of this spray putty, in fact, it is the only product i use to smooth and fill layer lines in my 3d printed props.It dries quickly but it's still tacky, therefore i usually leave it for 2 or 3 days to make sure it hardens properly (keep in mind i live and use it in a humid area so this might be causing the long drying/hardening process).It has excellent filling properties and it's easy to sand (usually I use straight 1000+ grit wet sanding) and it comes out absolutely smooth.The product says to use a clear coat to seal it before painting but i skip that step and so far had no issues with the final result.

Give a good 24 hour before doing any work over the top,,if you don't deal it it can cause paint shrinkage...

I purchased this to fill in layer lines and smooth out 3d prints on things I wanted to paint. It works very well. I have never found a primer that can properly fill the layers as well as I wanted but this does the job perfectly.I've tested various methods of sanding using different types of paper and grits. I found that best process is several light coats of the putty, 30 minutes between coats (it's actually touch dry in under 10 minutes with thin coats) and then overnight after the final one to let it totally set. I then use wet sanding with 400 grit sandpaper - careful here it makes for a very messy worksurface and hands, use gloves - leaving about 1 hour to fully dry again and then finished it off with dry sanding (do this outside and with a mask if you have one, particles go everywhere) using 1000 grit sandpaper. Things are unbelievably smooth at this point.After that use primer and then paint, should come out awesome :) I have spray painted directly onto it WITHOUT primer as well and it worked just fine however I still suggest you prime it just to seal the putty layer against any moisture (which if the wet sanding is anything to go by it won't stand up against being wet for too long without a sealing coat of something).No clue how this works with cars haha

I was a bit sceptical looking at the previous comments on this stuff but for the price gave it a go, this stuff is great I normally use Motip Spray putty but that's getting quite expensive now.Once opened and given a good shake the spray was great, sticks really well and dries quite quick, yes it smells but not as bad as others I have tried. Once dried it's easy to sand and you can paint straight away. Love it and now it's my go to for spray putty.

Great use for 3D prints and filling in the gaps.Like others I struggled to find a decent filler that filled in the gaps or was easy to work with. I brought 2 for my current design and they did the trick.I did a few thin layers until the gaps were covered, leaved for a 3/4 hrs to dry when done. I used a primer and finishing spray afterwards.It leaves a grit like texture afterwards but is aesthetically pleasing. In general the process of filling in small gaps was best so far but would still use filler for larger holes/gaps.
