Hey guys,
I had used some of my buddies filler as of late but I am unable to get it at the moment.
Did a little searching and I'm leaning towards automotive spot filler, also heard good things about Tamiya. What is your go to? Just using it for rolling stock and locomotives to fill class lights, smooth sides etc.

I haven't used any in a while but in the past I used Squadron Green putty. I wet sanded it and it seemed to work well. They also make a white putty which some may use as it may be easier to cover with paint.
I used the green on my ADM Grain Elevator to hide the seems in the silos where the parts joined. OTOH, being able to see it helps you with the sanding and smoothing process; OTOH, you need to cover it up so it doesn't show through on white plastic.

Ever since I went to using spot putty, I have never touched Squadron again, and I am A-OK with it!
Also a big fan of Mr. Dissolved putty for super fine work, as you can also put it on with a brush.

I've never gotten very good results with Squadron, but the Bondo automotive spot putty has worked very well for me. I've heard good things about Tamiya putty, but considering the easy availability of the automotive putty it never seemed like worth trying to track down.

I use both the Squadron and the Tamiya. I like the squadron green for larger areas/gaps. The Tamiya is thin and has a consistency close to paint but its great for scratches and gouges. I has a brush in the bottle and goes on very easily. Unfortunately I don't think theres one product that does it all.

I'm not a fan of the white Tamiya stuff, which is the one product of theirs I don't care for. I use Bondo spot putty for just about everything. If you need to fill a round hole, I would say first use a piece of plastic such as Evergreen rod or sprue* from an old kit as a plug, then Bondo around that where the fit isn't perfect. Use styrene sheet or strip if you need to fill rectangular or square holes, and again Bondo around that. If you're trying to fill holes with Bondo or any other putty you'll come up short.
* An old trick to get the right diameter for a round plug is to heat some sprue over a candle then using pliers pull it apart. You'll have an elongated cone shape that you can press into the hole you need to fit and just trim off what doesn't fit.

In my experience, Squadron putty (white or green) always shrinks and cracks. Say you pull an airhorn out of a shell that leaves a 1/16" hole and use Squadron to fill it. Put it on, let it dry, sand it smooth...and you'll soon have little 1/16" dia. divots. Say you remove a 48" fan, fill the hole with styrene then seal the edges with Squadron...and soon you'll have a 48" diameter crack.
OTOH, when I've used Bondo, it doesn't crack or shrink.
I will never use Squadron putty again.

I don't have the patience to wait hours and days for squadron green, and I never liked the results after sanding. I've got a tube of Kombi automotive spot putty, and never looked back. It dries to a sandable finish in minutes if the coats are thin.

I had a tube of 3M Blue Acryl for years - great stuff, never shrank, never cracked. But I tossed it when it had started to dry out in the tube. I've used Tamiya since then with pretty good results. To me, putty is only for very small cracks and applied in very thin layers. Recently I tried the Mr Dissolved Putty - it works quite well indeed.

Mr. Dissolved Putty is superb stuff. I use it on plastic and resin kits...really works well.

. All fillers that are ready to use out of the tube, set by evaporation and will all shrink to some degree. That may or may not be a concern depending on what you are filling. Noted. When reading the ingredients on spot putty, it's clear that people have made some pretty exotic blends to minimize shrinkage, but in principle if we keep the filler layers minimized it helps. Not sure how I would feel with a 2-part mix, as working with any bondo variant is inherently an exercise in panic. |
