I just finished shaping my first board and it came out surprisingly well for a first time. I will now spraypaint directly on the (PU) foam as I dont want to mess aropund with tints etc to keep it simple. I have a couple of questions though:
1. it is obviously a perfectly white and nicely sanded foam now - do I need to use an acrylic white base primer underneath or is this not necessary?
2. am I right in understanding that I should seal it afterwards with acrylic varnish before laminating?
3. I do not fully grasp the concept of a freelap, yet. In my understanding a cutlap produces a slightly darker shade of the same color around the rails - would this also be the case when not using tints but just the resin and the same two layers of fibre? If i end up with a darker color where at the overlaps then I prefer to have sth neat and clean and would rather opt for a cutlap. Thanks for your advice - I struggle to get my head around that and cannot find any good explanation on the web.
