Tips

Be careful when doing any touching up as Halfords paints lifts most varnishes
Do not spray Cellulose based on top of oil based.
Some people only use gloss as its easier to apply lining; varnish matt or satin after.
If using satin black use matt black first as it flows better into nooks and crannies better than satin.
