[quote]Hi NeilMy name is nick also small shop owner from the uk
Also a lesonal user.
You may have left it to long as suggested above, 20 mins may have allowed case hardening where the outer shell of the paint started to cure.
When you put the lamp on it you drew the solvent through the part cured outer skin on the paint surface.
To be honest i have never been a fan of heat lamp on solid colour’s i have seen them pop to many times.
Also you mention three coats, i know reds can be bad on coverage,
but maybe two full wet coats might not have been as prone to pop.
i think thats where the problem originates, i would def try and stick to two coats if you want to use your lamps a lot.[/quote]
Hi nick, good to see another uk owner here.. 😉 yeah will try putting on straight away on next job see what happens, yeah i would usually use 2 coats no problem but this was a weird red,washy, really clear and didnt want to cover primer at all.. thanks for your help

[quote]i would put the heat to it right after spraying. paint can be funny with dry times. if you let it sit 20 mins. to air dry, should of left it alone.[/quote]This can be true depending on the product and application. Maybe the product you used was too fast and the heat lamp helped it skin over trapping solvents in. A slower activator and/or reducer may help.
Read the tech sheet for your paint as well as the heat lamp.
macioce made a good point. Some infared lamps cure from the bottom up others cure from the outside in. This can greatly affect the way you dry your work.[/quote]
Yeah this is what i was thinking, should i use slower activator and thinners then if i know im going to be using the infrared on it?
i used fast activator and fast thinners (reducer i think some of you on here call it :cheer: ) as was only doing 1 panel
