Gorilla Glue Superglue on painted surfaces

[STARMAKER.REBEL]

I find that cementing parts together that have been painted before cementing don't stick together well. MR Cement doesn't stick well on painted and neither does the Tube of CEMENT that I can't seem to find in the abyss of my bedroom. I'm using Gorilla Superglue and that works well on painted parts. My bottle is almost empty though.

To use most model cements, you have to scrape the paint off where the glue is to go. This is relatively easy for things like fuselage mating surfaces, but can be quite hard for small detail parts. Some amount of touching up is usually required, too.

This is why I prefer to build and paint the inside parts of an aircraft model completely, then glue the fuselage parts together, mask off any clear bits, and only then finish the rest of the model and paint the outside.

My new problem is that I have too much Pencil graphite on the top Half of the Helicopter. I tried using erasers and they don't work and just foul-up the paint. It looks horrible now...

Okay... I found out that if you rub really hard on the pencil graphite with your thumb the graphite comes off. I'm not saying to try this with cemented parts! It works well with Gorilla Glue Superglue but you have to use a tremendous amount of force with your thumb and Cement might not be strong enough. The problem I have now is the superglue leaves bad marks on the joint. I will circle what I mean in these photos. (This is my first time useing pencil to outline the panels. Is there a way to make the lines deeper after painting them?)

Thanks for your HELP!!!

When I paint parts before gluing I use liquid mask on the areas that will be glued. Paint the part and remove the liquid mask. Best way to prevent a glue/paint mess. You can scrape it off but then you risk scraping the paint you don't want removed.

Rubbing with a moist thumb will remove graphite quite well from smooth surfaces, like bare plastic or (semi-)gloss paint.
