Hello,

Can anyone recommend any alternatives to 2k paints / primers and fillers for sealing bucks etc.  Is seems 1k systems will be problematic with bonding / mould releasing but 2k looks like evil stuff to work with and prohibitive cost wise for me due to the H&S kit required (3 stage filters for breatheable air supplies, secondary compressor, air fed mask etc..).

Is 1k completely off limit or is it just that it's hit-and-miss to avoid problems?

1k paints dry by solvent evaporation basically the longer you leave it the harder it gets, 2k paints dry by chemical reaction which is obviously why there is a catalyst. the aerosol 2k paints that are around nowadays are good for the shall we say handyman at home (even though we use them at work for painting inside rear panels and 1/4 panels before bonding and riveting)

used in a ventilated area with a good mask you'll be fine, don't forget to keep as much skin covered! it does absorb chemicals.
