Lotta people use pill bottles.

If they're styrene bottles, they glue much better than most rattlecan tops will.

Noted thanks for the info… is there a specific glue to use in this application or is it just a pain in the butt either way?

The plastic can caps are made of doesn't take glue well, but in my experience neither do pill bottles, which are made from Polypropylene, not Polystyrene. At leas all the amber color pill bottles I deal with.  Their recycling symbol is #5 PP.

My most recent amber prescription bottles (2020) are marked PETE, polyethylene terephthalate, recycling #1, which will bond kinda OK with CA or epoxy if roughened, but much post-bonding handling is asking for failure.

CA adhesion to PETE and other "low surface energy plastics" is enhanced by using Permabond POP primer or similar "adhesion promoters", and of course there are bonding materials designed specifically for this purpose, but the average modeler isn't going to buy expensive 2-component industrial adhesives.

PETE and PETG are frequently used for replacement clear model car parts like windows, and are often held in place with PVA (the white glue family). But the bond isn't very strong, so fit needs to be precise and post-gluing handling should be minimal.

Also please note: I specifically said: "If they're styrene bottles, they glue much better than most rattlecan tops will".

I have had older bottles made of styrene, which is why I mentioned them.

Why do you think I'm arguing? I wasn't even making a counter point.

I simply conveyed my experience as we usually do in online forums.  Isn't that what the forums are for? To share modeling experience. All the amber bottles I have in my possession, some still with the current medication in them, and ones I collected over the last 20 years are made from Polypropylene.  I also know that (as you also mentioned) most glues used by average modelers do not bond Polypropylene or PETE well.  Using those materials for tubs usually means that they will likely be exposed to a bit more structural stress than a windshield.

That's all I did - no  need to get your feathers ruffled.

Call it whatever you want.

I said IF they're styrene pill bottles etc. etc. etc.

You said pill bottles are not styrene.

Looks like we were talking about apples and oranges.  You mentioning Polystyrene bottles should not exclude me being able to mention Polypropylene bottles. My response did  not dispute your pill bottle experience - just added my experience.

But I apologize for adding my modeling experiences to this thread. :(

Oh please. Call me out when I'm wrong. Fine. I don't want to post misinformation.

But half the time you call me out because you didn't fully read what I wrote, and it gets old.

The ones I have are #5 plastic and Tamiya thin cement has zero effect on it.

And just so there's no more confusion, nobody said solvent cements work on all pill bottles...ONLY THE STYRENE ONES.

YOU may not have any, but they do in fact exist.

Bill, this is getting silly. Please reread my original post. Where exactly have I contradicted your statement, or called it wrong? I simply mentioned that all the pill bottles I have dealt with were #5 plastic. Why are you insisting I'm arguing with you? I'm done!

It all started when you called Peter a low energy plastic.🤣🤣🤣🙄

Guys I’m a noob trying to learn… that is what this post is about… I love you guys but let’s just post about our experiences… I think I have an adhesive idea I’m going to try but let’s get along and help me and other new guys get better and we’ve gotten to a different path in this post

I think the problem started when Pete thought Bill was talking about Pete. Not polyethylene terephthalate (PETE).🤣
