More thinking, I'd tend to prefer CA over 5-minute epoxy. The 5-minute stuff doesn't stick particularly well to ANYTHING in my experience.

I also found this on one of the "practical machinist" sites that have people who actually DO stuff, rather than endlessly-repeated but untested opinions. " I always use Devcon Plastic Welder[22045?]. It's part epoxy, part meth-methacrylate[dental acrylic]. Seems to work better than most other types of adhesives for non-bondable apps." And this: '"A loctite applications engineer recommended this for delrin to aluminum.Rough up delrin770 Prism PrimerLoctite 401 "

I did a little more digging, and this hardware-store product by Loctite specifically mentions Delrin as one of the plastics it's effective on. As it also bonds a wide array of other materials too, it might be worth at least trying it on your application, as whatever is left over can be used as a conventional medium-strength epoxy. http://www.loctiteproducts.com/p/epxy_plstc_s/overview/Loctite-Epoxy-Plastic-Bonder.htm

If it really is under "no stress at all", your "scuff and CA" idea ought to work. After all, even very slippery polyethylene bondo-spreaders will get bondo stuck to them...and sometimes it's hard to remove entirely...as the surface becomes more and more scuffed with use. 120-180 is probably a good guesstimate grit to use. All I can suggest is that you test the bond strength somewhere other than on the model first. And I'd be VERY interested to know your results.

I find I need to be pretty focused while designing, fabricating, welding, machining or testing real-world parts and assemblies that have to function reliably in three dimensions, and particularly while diagnosing problems or designing and integrating electrical and electronic parts and applications. I guess that requiring focus to do these old-fashioned things, I must be pretty stupid.

Delrin is generally thought of as a self-lubricating plastic, due in part to its "low surface energy", similar to what makes it hard to bond to polyethylene. When I fabricate something from it (like suspension bushings or clutch pilot-shaft bushings) I always design so the part is a press-in or snap-in fit. However, it CAN be bonded to itself and dis-similar materials. Here's how: http://reltekllc.com/adhesivesfordelrin.aspx

Wow. I have to actually WORK during business hours. I guess that's an old fashioned concept too.

Steve...prior to plating, what sanding grit do you take your work on the bumpers and parts to where you've removed mold lines or made other modifications? And can those guys plate over correctly finished epoxy or bondo on customized parts?

Just a quick additional comment...I'm not opposed to the idea of smartphones and I believe they're great tools, just like a lot of other great tools available that help humans do a lot of things (I'd rather change a flat tire with a jack and a wrench than a stick and a pile of rocks...unless there's a phone app for that now ). Seriously, because today's hand-held processing ability is so huge and speech recognition is just about on a par with a human helper, I see a smartphone in my immediate future. It would have been nice to have in-vehicle access to some internet data during my last trip, for instance. Handy, but certainly not indispensable. During my recent 10-day drive, I did have to stop at a public library and get online for a few minutes. Once. My paperwork is also done mostly electronically these days, but a smartphone isn't appropriate for it in my own case. A laptop is pretty much mandatory for the lengthy and detailed documents I have to prepare. What I DON'T understand is the constant need to check and update one's social network "status" on a minute-to-minute basis...and it's this that appears to me to be what most of the smartphone addicts are doing. Is it REALLY so important to know where one of your hundreds of "friends" had lunch, took a dump, or bought shoes? And does the rest of the world REALLY need to know about the most trivial and insignificant happenings in your daily life, or your inane and uninformed opinions on world events, or what infantile celebrity-behavior has the trending-world all atwitter at the current instant?

I followed you build thread on this one with much interest. Very nice innovative concept and techniques to achieve it. Beautiful work, as always.

No smartphone, no tattoos...though I've been in one of the classic environments where tattoos were a little more than me-too me-too fashion statements. I even get ticked if someone calls my coal-burning cell if it's not a life-threatening emergency. I recently spent some time at the Grand Canyon and was amazed at the number of people looking at their phones, and the number with their backs to the canyon, taking selfies. Being where-you-are, with-whoever-you're-with, and in-the-moment seem to be decidedly old fashioned concepts. PS: Nevada has apparently passed a no-phones-while-driving law that is being actively enforced. $250 fine for first offense if what I was told by the car rental agent is correct. Good job, Nevada. PPS: Paper MAPS still exist in the world for people who prefer to use them...and can. Somehow I managed to drive a couple thousand miles with NO GPS or moving map. Didn't get lost once. Simply amazing, eh?

I believe there's a front bumper for that DeSoto in the old AMT bumper parts pack...(upper right, upside down)

Doesn't have quite the same curb-appeal though...

Here are some links for specific info and procedures. While Joe is entirely correct about the effects being less-than-permanent, especially if handled, you CAN use a spray fixative or even dullcoat to make the effects quite stable. https://www.caboosehobbies.com/catalog/techtips.php?techtip_id=5 http://cs.trains.com/mrr/f/88/t/181333.aspx http://modeltrains.about.com/od/modelrailroadtrains/ss/weatheringwithchalks.htm

Model train guys have been using chalks for weathering for decades.

And Spaxstix makes a color-flop rattlecan product for models...

Oooooo...fake hood scoop...or the old-favorite: massive over-carburation with two 750-double pumpers on a tunnel-ram manifold, long shackles with the ass way up in the air, silly-wide rear tires...you get the idea. Engineering-free doofmobile, built to the fashion of the day. Evil-handling and slow gas-hog, with a bunch of mismatched bolt-on "performance" parts that don't work at all.

I don't know how old you are or what you want to do with the rest of your life, but that seems like it could possibly be a stepping stone towards getting your A&P license (airframe and powerplant mechanic). With a technical background and working for a while in the aviation industry at an FAA-certified location (any company working on jet engines and flying APU units will have to be an FAA-approved "repair station"), it's not all that much of a jump to getting your license. Once you have it, you're employable anywhere there are aircraft. There's a shortage of good, qualified licensed A&P techs. You write like you have a functioning brain, so the test-taking part of the A&P licensing requirement should be easy for you to pass, especially as you already have some hands-on technical experience and presumably a good degree of mechanical aptitude. While there are diploma mills that charge a lot of money to get you certified, YOU CAN DO IT ENTIRELY ON YOUR OWN. Getting a period of hands-on experience in an FAA shop and studying for and passing the written and practical tests is all it really takes.

You know, I might have to consider that for a retirement option. Furnished air-conditioned room, three squares, free medical and dental, library, gym; hell, what's not to like?

"My mother-in-law insisted we get a silver car"... "All the neighbors really like it"... "We went to a show and saw the new Baaamobile concept car"...

Yup...in scale too. Several issues (more than shown below).

i'm having a hard time seeing Revell doing the G-body Monte in 1/25 when it already exists in several versions in 1/24.

Actually, though similar in concept, the rear windows on the two cars were in fact different, developed by two different methods and design teams within GM (if I recall correctly).
