hi peeps heres some work ive been doing on my vw corrado vr6, just about ready to add some 2k primer,
my question is! its starting to get colder now the summers over, just looked at the max temp in our local
paper and it says 15c so min is probably 10c, is that going to cause problems?? or just delayed drying times?
and would that cause problems with solvent bascoat?? or 2k clear? thanks...
all badges and holes welded up!
i guess i should make a thread in the members project section...
spraying 2k primer when its cold?!

well i'll sart this debate, as i shoot in temps from the mid 40s to mid 50s in the winter sometimes colder but we won't talk about that now, and everything is fine. epoxy may give you some problems ,but i have shot ********** epoxy at just below 50 and it worked perfect. 2 wet coats and it was hard as a rock the next day ,i did give it about a 20 min. induction time. i would like to see you feather those spots out a little more, i would da all the paint off that rear panel sure you can fill it with the 2k primer but you should try and get it as flat as you can first it will sae you in the end

Unless they changed it,,,the min temp should be no less than 65 "Degrees"

Should be no less than 65, but would you do it if you needed to or would you not take the chance? 1997 S10 p/u.2005 5.3 L33 LS swap. 5spd, ZQ8 susp, 76 mm turbo,565 rwhp.610ft-lbs torque. Tuned by me with Efilive. Polo green metallic.

I am in the same position although I can heat the garage if I want. Its a pain in the rear to heat and ventilate and all that bs. Im using propane so the fumes arent real bad but still there somewhat. 1997 S10 p/u.2005 5.3 L33 LS swap. 5spd, ZQ8 susp, 76 mm turbo,565 rwhp.610ft-lbs torque. Tuned by me with Efilive.

Here's the recommendation from the ********** tech sheet for epoxy:
Cold Weather: In cold shop conditions this primer can go dormant. Try to keep heat on car for four hours after spraying with a minimum metal temperature of 60° F. Also, when cold it will help to mix primer and let it induce 60 minutes before spraying. Application of any epoxy in cold weather can destroy a paint job. If you have any questions regarding the application of ********** Epoxy in cold weather please call us first. Metal temperature when you spray is critical and must be at least 60 degrees! The epoxy CAN stop cross-linking when metal temperature drops below 60 degrees. I usually warm the booth area to a minimum 70-75 degrees and make sure the car is in there long enough to warm the metal to at least 60 before I shoot. Then keep the heat on for a couple of hours after that for the epoxy to cure. Metal is slow to warm when cold and retains some heat once its warmed. As always the tech sheets are going to err on the safe (warmer) temperature side so as to prevent issues and customer complaints. Can you get away with 50 degrees? Probably but I do not think it is worth the risk myself. You should follow badsix's advice on feathering out those spots. Generally you want to extend your filler well beyond your repairs and then block sand them. 1968 Coronet R/T

To answer your original question about 2k primer (I'll assume you are referring to build primer and not epoxy) it can be sprayed in low temperatures but you will need longer flash and cure times.

you can get small infra red heaters for not much over £100.I'd get 1 of those and heat up the metal before you put the paint on.Nothing worse than spraying onto cold steel
