Hi all
Looking forward to the decent Christmas break and wondering what jobs I can get on with.
One of the things I'd like finished is the rear lights but the housing need spraying. I've read the aersol instructions and it says to keep
at a certain temperature hence they're in the house.
My question is though as long as everything is ready to go and it isn't too windy is there any reason I can't go straight out with a pre
shaken can and spray if it's cold out?
Common sense says i shouldn't but is there any reason the paint won't work properly?
Cheers for the patience with the continuing daft questions.

I did some spraying from aerosol cans last night in the garage, I had an electric heater in with me and a hair dryer, came out really well
Presumably you need a certain amount of heat to make the solvent evaporate (otherwise it'll never dry!!!!)
Need to spray outside because of the car. If I sprayed outside then moved the bits into the pre heated garage with the heater on to dry would this
then be okay?
Thanks for the prompt help it's much appreciated.

Presumably you could bake the paint with an IR heater. That'd work okay outside (unlike a radiator type heater)...
i use a heatgun when painting, heat up the thing you want to paint, then spray, then use heatgun after.
hair dryer might be a bit more kind as the heat gun can boil the paint and cause little bubbles

Hi Nigel
I keep spray paints inside (warmed in the airing cupboard prior to spraying too!!) but be careful when spraying cold parts in the garage due to any
condensation that may be present. I generally warm the components prior to spraying if i can (again in the airing cupboard) before spraying
outside.
An IR lamp might be a really good idea. You can get a 1.3kW heater off ebay for not a huge sum (

ZViewItem) and it can be used for curing paint, warming you in the garage etc.
I will be looking for a 3kW version shortly for curing powder coat!!
I made the mistake once of spraying under a bonnet after dark, although the panel looked dry, it can't have been as it rusted only a month after
very badly

I spray R/C car bodies outside here in Canada in winter. Put the spray can in warm water for about 5 minutes, spray the item, then if possible bring it into the house and hit it with a hair dryer on low heat from the backside of the item painted. works for me
If I'm spraying in the cold I stand the aerosol in a sink of hot water for ten minutes then give it a good shake before applying it. I warm with a hot air stripper held at a distance or a fan heater parked behind it if it's big.
don't you just wish you lived in a warm country...
Yes, and I used to too: our West Coast, which is just like your weather. In other words, terribly humid and crappy for spray painting. I used to have
a hell of a time spraying guitars outside then moving them in to dry. Never worked very well.
Now I don't even bother going outside (now that I live in a cold place), just do it in the basement with the window open.
Thats why I put an 80,000 btu gas furnace in the garage.
But we get 6 months of winter and 6 of poor sledding.

i use a big cardboard box with a fanheater in as a mini spray booth.
becareful spraying outside in the cold coz it'll bloom with the damp?
