Chevy II Posted February 3, 2023 Share Posted February 3, 2023 I know you’re supposed to scrape painted surfaces before gluing them, but what about when you are unable to scrape a part before attaching it. I have been using ca glue to attach painted pieces. Haven’t had a big problem so far, but just read an article that said never use super glue to attach painted pieces without scraping the paint from mating surfaces first. What are others doing?

Classicgas Posted February 3, 2023 Share Posted February 3, 2023 Just wondering why you wouldn't be able to scrape the paint off? Quote Link to comment Share on other sites More sharing options...
Shark Posted February 4, 2023 Share Posted February 4, 2023 If you can't scrap a painted surface, I use 2 part epoxy glue. Have had super glue to frost finishes. Quote Link to comment Share on other sites More sharing options...
Mark Posted February 4, 2023 Share Posted February 4, 2023 It will stick to a point, but only as well as the paint is sticking... 3 Quote Link to comment Share on other sites More sharing options...
Sidney Schwartz Posted February 4, 2023 Share Posted February 4, 2023 I've not had any problems using ca glue on painted pieces, and I don't bother to scrape the paint off unless it's to get the parts to fit better. I prefer the thicker, "gap filling" ca glue, partly because it takes slightly longer to set. I can apply it to one part and then fit the parts together. This avoids getting the glue on the surfaces that show. I also use two-part expoxy glue for pieces that may be subject to more than usual stresses. Canopy glue for clear parts, and plain old Elmers for test building. Quote Link to comment Share on other sites More sharing options...
jaymcminn Posted February 4, 2023 Share Posted February 4, 2023 Bob Smith "Super Gold +" is my go-to CA adhesive. I've never had it fog up on me. There's no need to scrape paint before using CA, but CA glue has no "give" to it. If you bump a mirror that's attached with CA there's a better chance the mirror will go flying, and a very good chance it'll take the top layer of paint with it. 2 Quote Link to comment Share on other sites More sharing options...
bill_rules Posted February 4, 2023 Share Posted February 4, 2023 The nice thing about using CA is if you drop your model, it basically becomes a pre-finished kit to build again... Quote Link to comment Share on other sites More sharing options...
NOBLNG Posted February 4, 2023 Share Posted February 4, 2023 Things like mirrors and door handles (and all sorts of other parts) I like to add a pin for a mechanical locator and CA to attach it rather than just CA alone. 2 Quote Link to comment Share on other sites More sharing options...
