Hey guys,
I did some mixing & matching of white & grey acrylics & got the perfect color for the belly of my Su-27 belly(I dont have an airbrush) but when I got down to applying it, it gets all rough & uneven. The belly does not look too nice. Its not smooth. In some places it is really concentrated. Its very rough all around. How do I solve this. Since its the belly I am not too bothered much but it cant be this way on the back of the a/c. Someone had earlier suggested the use of primer spray. Does this help or are there any other tips/solutions that you can give me about this problem please? Before applying the paint I did not add any water or thinner.
Cheers & thanks in advance,
WD.

Most people nowadays are using an undercoat. Many swear by the use of 'Grey - Primer' which is a spray Acrylic. Two advantages, the first is that it 'keys the surface of the plastic (to allow paint to adhere better) and secondly it shows up any imperfections which can then be arranged.

To thin Acrylics, use distilled water (or in the case of Tamiya) alcohol can be used. Tamiya Acrylic is like putty when using a brush....

Another thing which you could consider, is a series of coats, don't try to cover everything with one thick coat. Rather 2-3 thin coats should build up the density/color nicely.... Jim

Good advice above..1st is a primer coat..2nd. Tamiya, I feel, Is the worst paint to try and brush. Whichever acrylic you use, thin it to a 60/40 ratio (60% paint) and put on thin layers to get to where you want. Very important also is a good brush.

On another note..did you wash it down with mild soap and water before painting?
If you are really unhappy to this point you can also remove what you have done and start over...just another option!

Thanks for the help guys. I scrubbed my belly with luke warm water & it did help. Since it is the belly I am not too bothered but for the back I will make sure that I get it right.
