Some of the spray paints on the market today are poor quality to say the least. I am finding the ones that smell like nail polish to be the most problematic. Judging by the smell, they must be based in acetone.
Yesterday I painted a mower base and this morning it looked great. I opened up the shed and let the sun shine in on it. Within a few minutes I noticed pimples suddenly forming on the surface. So I pulled the door down again. Back in the shade it is behaving itself. I am not game to introduce it to the sunlight too quickly in case it all goes bubbly.
Another problem I've had with this paint is it sometimes "crazes" around the edges (forms patterns like cobwebs), even though I was careful not to spray too heavily.
On another occasion I painted a starter winder one day. It looked perfect, but I could still see primer through it in places. I decided to give it a second coat. Within a few minutes of applying the paint suddenly went really crinkly, like it was reacting with the earlier paint! I've never had this happen before.
I blame the paint. Something is just not right with it. It is very hit and miss. Most times it goes on great and leaves a shiny finish. Other times it just goes crazy and there seems no logical reason for it.
