i dont post much but i'em on here reading everyday,
i do alot of painting (see my showroom for some of my work) and i have encounterd alot of different paint problem's every type of paint that you paint with has a catalyst (cureing) some are a chem some are water ,and some are air.so every time you are going to paint you have to add that in with relation to your project type of material (ie) wood,metal ,plastic ,paper etc,etc,etcto the type of paint you are going to use,for example you would'nt really want to use a heavy chem catalyst on MOST! plastic due to the HEAT caused by the chem (catalyst) reacting with the air to force the drying process. most over the counter CAN! automotive paint's have a high part of catalyst to paint to ease the unknowledgeable consumer with use of the product. (in no way em i saying that your are unknowledgeable just trying to state a point)Than there is the primer issue not all primers are the same ,some primers will actually mess up a project due to reactions with the paint that is sprayed UPON! it ,and also on the starting product that it was painted on.i could go on for day's about the whole paint process,but we will save that for another day,after reading your question,is there a chance that you painted that body at night,are on a cold day, the very first thing that i do when i paint is make sure that my paint is warm ,and also if i can get what ever im going to paint warm also. if you go to paint and the can is cold are the project(body) is cold when you spray, you will get coverage at first than a little time later you will get a contraction, do to the catalyst having too cold of air to start the reaction(drying) wich in results in a ripple effect,sometime's a cracking effect,and yess even the bunched up in spot's effect,some of these are cool if you are going for that effect.but not good for the solid color look,kinda think of it as the oil and water theory,but with chem and paint,,there are alot of different things that could have gone wrong,you could have even gat a bad can,but as was said before try to stay with the same company of paint through out your whole process,MOST! paint is developed that way,the best paint that i have ever used for my body's is PACTRA comes in can's and also airbrush bottles,hope i was somewhat of a help if you have any questions that you would like in more detail i would be happy,also one more little helpfull hint is if you are unsure of the paint on the body do atest spot on the inside some where ,see how it come's out might save a little headache.
