Why did you need Tech help? Can you not paint your own boat? Did you try to cut corners (because it was so expensive)? Did you try to use it for something it was not to be used for? Can you not read the directions? Did you attempt to talk to tech help and not give them the whole story because you were embarrassed of what you may have done wrong? Did you prepare the area properly?
Yes, Pettit is a good brand. No argument there at all. But Interlux is a good brand, also, with excellent tech help, in my experience. Let''s see - you painted the top of your, what, maybe a 30 foot boat. I''ve done over 50 boats with Interlux products. Tops and bottoms, varnishes, repairing blisters, etc.
Unless you want to give your whole story, bit by bit, allowing yourself to be open to criticism, don''t badmouth a product that has a proven track record. Please tell us your story, bit by bit, nothing left out. Then we may find creedence in your accusations.
