Putty,s

Sure, I use Bondo glazing putty all the time. it is a 1 part filler that comes in a tube and is packaged on a blister pack card and is sold at Wal Mart and auto stores around $5.00. Dries fast and sands great!

In the UK Halfords Automotive sell Cataloy Knifing Putty, About UKP£2.99/USD$4.50 for a 100g tube.

However Deluxe Materials Perfect Plastic Putty (youtube link) is now my tool of choice.

Pretty good stuff & it doesn't react at all to plastic

Thats great information, Thanks

I second modelmaker66 opinion.  Bondo 1 part glazing putty is all I use.  Nice that I can just buy this off the shelf at any auto parts store and be using it within 5 minutes ,and no shipping or waiting 2 weeks to get it.

Auto spot/glazing putty is my goto.  Have used it for years.  Only caution is to be sure to replace cap rapidly. It is one thing to lose a 2 oz tube of putty to drying out- different for an expensive one pound tube!

Halfords Automotive sell Cataloy Knifing Putty = Bondo.

Still use the knifing putty, but the cleanup & shaping is far easier with the Perfect Plastic (for me) than the automotive.

I used it to fair-in a hefty wing fillet that beat everything else I'd tried.

When buying the Bondo in a tube be careful you do not buy the two part version. They look very similar. The two part version will have a large and a small tube inside. The small tube is easy to overlook. Its sometimes behind the larger tube and very easy to miss.

Absolutely. I don't see how other putties can possibly be better than Perfect Plastic Putty.  It's one of the greatest inventions for modeling ever.

What makes it such a great putty. It has to react to the plastic some what for it to adhere.

Thanks for posting that link. It got me off my duff finally and I ordered a tube.   Been wanting to try it all year.

I do tend to agree with ...29's comment above that a putty should bite into the plastic a little, but still I'm looking forward to trying the PPP.

ME TOO. i may try thinning it with acetone to fill seams in dinosaurs where sanding would loose texture but for everything else out of the tube. it will shrink a bit so slather it on and deep sink wells may need a second application after drying and sanding. less expensive than squadron and doesn't dry out. just finished my first tube last month, couldn't get any more out.

Greg - I use both Tamiya and PPP, the latter is good for water thinning or cleanup if desired, for Tamiya I use Tamiya Extra Thin liquid cement for thinning. The cement makes the Tamiya a bit easier for application, and gives the filler a bit of "bite" for good adhesion to plastic surfaces. It also makes for a bit faster set up, when applying a little thicker amount. 

If I have to really ladle on a thick amount, like a wide seam or hole, then it's two part Bondo. It doesn't shrink or crack when applied in thick amounts, the other hobby fillers are prone to that as they set up, at least in my experience.

Patrick, thanks for the additional info.

I use Tamiya as well. It's my favorite of all the non-water soluble putties for sure. I've been thinning it with Acetone. I must try the Tamiya thin cement now, thanks for that.

I haven't tried Bondo yet but you and many folks here swear by it. Shrinkage is surely a problem with many hobby putties, so I think you've pushed me over the edge to try Bondo!

My PPP arrived and I've done some minor work with it. I like it so far.

What makes PPP stand above the rest of the crowd is that it does not shrink once it dries. It thins with tap water. It can easily be wiped off with a water damp Q tip in areas like wing roots, eliminating the need to sand. It dries super fast.

I used Bondo Glazing Putty and Squadron Green Putty for years but now PPP is my go to putty. 

Ernie, I hear you.

I'm all about water clean-up, and that is certainly a big plus for the PPP.

I've been using Tamiya Basic Putty thinned to whatever consistency I need with lacquer thinner. It works good. It dries fast enough. It does shrink a bit, so two or three applications might be necessary. I gotta get me some of that PPP though!
