Just my 2 cents guys but Thinking about all the work put into the bodywork and paint on something nice with all the work you have done on the rest of the car, I would not even cheat on low cost paint or primer. Sikkens is one of the best in my book but other top brands out there are also good. If you plan on keeping the car for a long time save up till you can afford to get the good stuff. That is just my Idea no harm intended
