I’ve never done bodywork or paint myself but I always hear that you have to stay with the same brand all the way through or there may be reactions is that the same with clearcoat do you need to run the same type of productRuns on the first coat, wow. What a clown. Even I'm not that bad. That sucks Dean.
I like what Jim said, carefully wet sand the whole car with 400 and start over. Any areas that he actually laid down flat you can just scuff and shoot over, any areas that popped or ran, you probably have to go down to the base again. Clear is pretty forgiving I bet you could shoot it yourself.
