Im using kill rust etch primer to undercoat my trailer and it says that the metal must be above 10degC. If i cant get it to that temp will it still be ok to paint it... will it just dry slower or will it not stick to the metal properly.

Anyhelp would be appreciated because im planing on painting it tonight.

Chemical etch primers need to be applied at the correct temp for optimal etching penetration. The paint will stick, but not etch as well if applied at the temp recommended. Also the chance of condensation gets higher as the paint dries - the solvents evaporate, cooling the metal and can condense moisture from the surrounding air onto the surface. Moisture bubbles under the paint.

And also the paint will go bloomy and your first coat do a mist coat first and let it dry a bit longer than normal before your next
