Question on two-pack paint

[peterh337]

Why not invest a little money in a portable compressor, an airbrush and some decent paint? Its not too expensive and its there for use for the rest of your life.

I have that already - an Evolution airbrush.

I even have a scuba cylinder with 1st stage and 2nd stage regulators, for portable airbrush use

But the damned thing takes such a long time to clean up afterwards that I don't use it unless the job is something worth doing right. Small touch-ups are not worth it - for all the masking one has to do.

peter that one did ring a bell and after having a quick google for the COSH sheet its one of the hardeners that will go bang if you don't do it by the book with storage and vapour.

Its also heavier than air so don't store it down stairs in a basement.

I might seem anal about this stuff but very early on after starting work the company I worked for didin't really control storage or for that matter had a clue what they had on the shop floor and there was a fatal accident.

Well I can confirm that without the hardener the paint had no solvent resistance whatever

I need to get hold of that hardener...

Two pages to get back to this point then peter.....

2 pack paint will dry out but not cure without the hardener. It won't weather properly or protect like that. It's 2 pack for a reason!

A little trick a friend of mine who runs an automotive bodyshop taught me was to make a little paintbrush out of masking tape. Roll it up into a cone and mix up a small amount of paint and hardener (not sure if you need to bother with the thinner, don't think that has anything to do with it curing correctly?) and dab it into the chip using the pointed end of your 'brush'.

As we're talking solid colours here you can then just polish it back flush afterwards - a lot less mess than using an airbrush or spray gun.
