How to get the best looking model when just using spray paint


Recommended Posts

you need to make sure the parts you are gluing are clean of paint before you glue them. you can also apply he glue with cocktail sticks or pins to stop from getting too much on which helps to prevent it squidging out when the parts are pushed together.

i typically glue pieces together that are meant to be the same color, and paint it as one.  if there is a piece that is meant to be different color, like say the exhaust on the chassis, i will paint first, and then glue, but only use a tiny dot of glue.

i like the model master glue with the metal tip for that. you can get such a tiny amount.  (not the testors branded one. that has a plastic tip, which is not as thin) https://www.amazon.com/Liquid-Cement-Plastics-1-oz/dp/B0006N6ODS

if its on the body, like say a side mirror, i will use the clear parts cement. its just white glue https://www.amazon.com/Testor-Model-Master-Cement-Window/dp/B0006NDZDU/ref=sr_1_1?dchild=1&keywords=glue+for+windows+model+master&qid=1610633387&sr=8-1 it washes off with water so if i make a mistake, it doesnt ruin the paint. however, you essentially cant touch that piece after. many times i will use the white glue to get it in place. when it dries, i will use the model master in a place not easily seen to make it more secure. 

 

i have recently started using the tamiya thin cement,  but i havent used it with pieces that are painted yet. that stuff seems to work good though, but does get rid of the paint it seems. its very thin, so i have to be very careful with how much i use. it seems to get everywhere if im not careful. no using it when im tired. i have messed up 2 models that way

 

one thing i have done, if i do mess up paint from spray cans. i will just spray some in a cup (not plastic cup) and use a brush to touch up. its never perfect, but usually quite hard to see if you build up the paint again slowly. a little at a time in layers

I would look for a different paint and glue.   There must be some sort of reaction going on there.  Try using a good plastic cement (not the cheap stuff) and keep the glue off the surface you are trying to paint.

Secondly, prime the plastic and use a good quality paint.  What you are describing should not happen if you are using good materials.

Yes, the Tamiya thin cement works well. But I only use it to combine unpainted parts. I learned the hard way about it seeping out and ruining the finish on painted parts.
