Since I am new to the group and working on my first model, I have a
question. What I am doing is painting the parts of the car first, and
then taking them off the template. I am having trouble getting the
glue to stick and stay. I have read that I should scrape the paint of
the glued area first and was wondering if that was correct. Thanks
for any help, and if some feel this is a stupid question I apologize,
I am still learning, and those that feel that way will get over it!
We all have to learn somewhere! I am very hooked!
I think you answered your own question: to adhere and properly bond the
plastic together the glued surfaces must be cleaned of paint, oils (from
fingers, etc.), dust and so forth. Otherwise any bond that does form will
be very weak and likely come apart. Hope this helps.
If you're using a solvent-based glue (Testor's, Tenax, etc.) you need to
be sure there's nothing between the two pieces of styrene you're trying
to bond. Grease, chrome, paint or pretty much anything else will get in
the way and should be removed from the gluing surface. If you're bonding
non-like materials (e.g., plastic to metal) the solvents won't work at
all. Cyano acrylic glue (CA aka superglue) and epoxy are alternatives
where a solvent won't work.
The template you refer to is the sprue, but what you describe is one method
Personally, I prefer to paint the parts off the sprue. I can't can't see the
point of painting on the sprue, then removing the parts, cleaning up the
attaching points, and then repainting those sections. Having said that, it
is applicable for some stuff (spray cans and small parts for example) but
it's not my choice.
Which glue are you using? I like the Revell Pro-contacta in the blue bottle
with the needle like applicator.
Yes, that is the correct procedure. Just remove sufficient paint for the
glued area. If you are using acrylic paints (and some enamels) you can cheat
and let the glue eat through the paint but there is the chance of mess and
No need to apologize for asking. However, if you start asking what is the
best airbrush expect screams of exasperation. It's the most often asked
question, which has no real answer beyond personal preference.
Excellent attitude. If you're specifically a car modeler may I suggest you
