SGloss Paint Finish

Hi, I'm quite new to model making and I'm having problems with the finish of gloss paint. After the paint is applied, whether dried or not, There are loads of tiny 'bits', almost like dust particles which is spoiling the finish. I've tried thinning the paint with thinners using various amounts of thinner and I've tried being very sparing when applying the paint to the surface. However many parts of thinner to paint I prepare, it makes no difference. It also makes no difference if I wash the model with soapy water. I've even changed my brushes.

This problem does not happen with Matt paint.

Any thoughts would be welcome.

Thanks,

It could be that the gloss finish throws these little particles into sharp relief. Ehen reading the model magazines one trick I have come across is polishing the gloss coat (and the underlying primer) with very very fine sand paper or a polishing cloth. It is likely that these are dust particles which stick to the paint while drying. Covering the model immediately after painting might help but this stuff is everywhere.

Hi Balman

How about painting with matt paint then use a gloss varnish afterwards. I know it's an extra step but if it cures your problem it could be worth it. I feel it's dust particals in the air as i've had a simular problem many years ago. Try covering the model with a raised plastic tub until the paint is dry, or paint one side of a plastic sheet and leave it upside down to see if the problem persists.Hope this helps

I've also heard people say that using a tack cloth (as used in full scale vehicle finishing) before painting helps, and that starting with a matt primer helps.

If you have tried using fresh brushes it's probably dust in your working environment. For gloss finishes your workspace needs to be a virtually antiseptic environment. Dust and vacuum everywhere and cover the model as soon as is practicable after painting. Even people who are completely adept at achieving good glossy finishes usually need to polish out particles that land on after painting. I'd recommend getting some micromesh in various grades and also some polishing compound.

In that case it is very probable that it is dust that is the problem.
