Flame treating

Do you have to flame treating or can you use a plastic primer?

    Depends on the type of plastic

    Yep time to search some. Lots of info (even a whole K2 video) on flame treating.

    In some cases, you'll need to do neither, some cases, both. Others, one or the other will do fine. ABS doesn't need flame treating and if you are dipping straight to it, you probably wouldn't need the primer. On HDPE, you'd need to flame treat and depending on the type of paint used, you may or may not need the primer.

    Also remember that some products are not known to work so well all the time with this process. Jim and some others have said the Bulldog adhesion promoter doesn't react well to activator. Do lots of research and buy the right stuff the first time and save yourself a lot of money and headache in the long run.
