Has the ideal temp for painting changed in the last 14 years?! 

BTW - 50F is the minimum...

Nothing sucks worse than dropping a side cover you just painted as you walk down your basement stairs though lol.

Dang. I'd forgotten all about that until you brought it up again...

I just painted with Duplicolor using an 8 oz. touch up can which is lacquer and it was cold(50)and wet outside. I had the steel fender inside at 65,so walked outside and sprayed one top coat at a time,then brought it back inside;I did 3 coats and the last(final)was the same result as the other 2,not a smooth shine,a bit rough. I'm sure the finish would be smooth if it was less humidity and 65+ degrees. I've find enamel is more prone to run in this weather but keeps it's gloss easier.

I want  to repaint my fuel tank using Duplicolor black enamel and then coat it with 2K clear catalyst paint. Do you know how long I need to allow the enamel to dry/cure a bit before I spray over it with the 2K clear topcoat ?
The weather here now is very unseasonably wet and humid 
I plan to wait until the weather is 70+ degrees Fahrenheit and dry before spraying the aerosol cans to coat the fuel tank. I never used the 2K clear yet;hoping it will dry/cure quickly so I can use the tank soon after.

I only have outside for spraying here at my apartment parking lot and so far it has been completely unseasonable as far as humidity/rain and low temps here.
The weather has finally got up into the 70's and dried up(37% humidity today)for almost a week now.
I need advice and pointers on using the 2K clear;I plan to clear a fuel tank and steel front fender which I've painted within the last 6 months.

I've decided to only paint on days that are too cold or too hot for the paint to set up properly.

Then I'll be able to blame the results on something else.

Wear the correct respirator and a full body coverage painting suit when spraying 2K clear, the carcinogens it contains are absorbed through the skin.

I understand.
Can you give me any other advice on applying the 2K clear ?

[Alan F.]

It's acrylic resin so it should behave itself and act predictably. I'd give your top coat an extra 24 hours dry time then break out the 2k, first a thin coat with a ten minute wait then maybe a second light coat and a ten minute wait then go with thicker coats.

There are lots of good youtube videos on this.

Alan,have you done 2K clear before ?
I imagine I need to wait 10 minutes between each coat,no matter how many coats.
My top coats have long since dried and cured months ago;how long does it take the 2K clear to dry/cure ?

[Alan F.]

I have not Bill but it's been on my list to learn about for quite some time so I've been reading here and there when the opportunity presents itself.

From everything I've read and seen 2K clear needs 24 hours cure time before you can cut or buff, some wait longer based on circumstances without any ill effects.

I needed to get this done.. well set-up outside today(85 degrees)and got started.  The wind was only 2mph when I started,but picked up to about 9mph while I was spraying and blew the paint away so that I didn't have enough in the one can to finish up.
I learned that,to do this correctly,it needs to be done in a booth under controlled circumstances;plus no neighbors around.
This 2K clear is toxic stuff and a person doing it needs the good equipment to protect their skin and eyes/lungs. I used N95 masks.. and did my best to cover my skin.
I'd still get another can of 2K to finish it up,when I'm away from the neighbors.

I'm going to get another can of 2K clear and finish this tank up;how long does it take to cure?
I'll need to get inside 4 walls and keep out of the wind;a friend mentioned going to a quarter car wash. I can spray it,then put it in the trunk of my car and go.

When I get around to my painting I'll be using many cans of cheap acrylic clear topped with just one can of 2K.

That sounds good.

I think the 2k will wrinkle the cheap acrylic and ruin your finish no matter how long you let the cheap stuff cure.

Sean,how long do I need to wait before I re-coat the 2K ?

I really don't know.  you need to follow the 2k manufacturers directions...to the T.  Not that useful discoveries are impossible to make through experimentation, but if you follow the directions, and the product fails, then that is a bad product.

I purchased this can from Napa;the Only directions on the can are temperature recommendations.

[seanbarney41]

Well, generally you want to spray the next coat right before it dries "tac-free".  Tac-free time is gonna vary depending on temperature and humidity.

Or go ask at NAPA.

I just learned that the problem I experienced was from an old can of Napa #7305 2K High Gloss Clearcoat..  Hey,the can was spraying dry,and spitting.
I've got to sand/smooth the clear a bit and this time  get a FRESH CAN of it. 

I went to Napa here in town yesterday and asked for a fresh can;they finally confirmed(after standing there waiting for 10 minutes)that the can on the counter,which I just slid my card and paid for was old. 
 I left without it,now I need to Look for a place that Will Confirm to me What a Fresh Can of Paint is..
