Engine enamel drying time

[Iain]

So I painted my engine block with 'Halfords High Temperature Engine Enamel' 10 days ago. I can still dig my fingernail in to the paint to leave a mark Used 3-4 coats to get a decent coverage within 2 hrs of eachother (like the tin told me to).

Why has this happened, and how can I speed up the curing process?!

heat

Dont believe me then....

Its on to thick an the first coats cannot dry out as quick as they "should" happens with all oil based paints when brush applied to quick so to speak.

Your best bet Iain is a hot air gun mate but it'll still take a while

won't running the engine have the same effect as heat gunning???? enamel paint always needs to bake on....thats what enamel is

Ah very valid point.

Propane torch it is then im afraid.

Sorry Benn course I believe you

I've been out in the garage with a heat gun, just wondering if anyone has any great ideas from similar experiences. Heard good airflow helps too so guess I can leave it outside in the sun tomorrow.

I did apply it quite thick within one day, but it needed it to get good coverage on the textured engine block.

Most engine enamels dont fully cure until the engine is run. Get it built and chucked in then run her up, its the only way you will get it to the right temperature without putting it in an oven.
