The beginners guide to...

I was asked the question what is the next step, after using filler.
I said to use very fine wet & dry paper and use a primer before painting/spraying.
Are there alternative techniques to this?

When I used to brush paint with Humbrol Enamels, I found I very rarely needed a primer.  Once I moved to acrylics, I found it was a must.  So you don't always need primer, depending on the paint type & brand.

There are alternatives to sanding when using filler.  I've heard it said that Mr Surfacer can be removed with lacquer/cellulose thinners, but watch out, as the brand I tried attacks plastic.

Vallejo Plastic putty can be used with water, just wipe it off with a damp cloth.  It's good for deeper, narrow cracks, such as those left when mounting perpendicular surfaces.

Correction fluid like Tipp-Ex can be removed with methylated spirits or Iso propyl alcohol.  I've used meths, apparently it shrinks less with IPA.  I've found it good for reducing panel lines, it tends to hold in shallower gaps than Vallejo Plastic Putty.

Many thanks.

I use "Mr Colour Thinner" to remove Mr Surfacer. Dosn't seem to effect the plastic but then it's a very quick wipe over with a cotton bud dipped in the stuff. Once Vallejo has dried it can also be removed with "Mr Colour Thinner"
