Paint problems
« on: March 17, 2017, 12:49:31 PM »


Hi All
I wonder if anyone can give me some advice on paint problems I am having with my lifeboat.
I sprayed the hull with Halfords spray paint. Left it about a week then lacquered it with Halfords lacquer.
I then left it for another week then placed the hull on its stand which is lined with felt.
Too my horror when I took it off again the felt pads have made an indentation mark on the lacquer, so much so that I will have to redo it.
Anyone knows where I am going wrong?
Many thanks in advance.

I seem to remember that Halfords white primer causes this problem.  Doubtless Stavros will be along to confirm (or not).

I had this. The cause was the paint while dry is still soft. The weight of the boat focused on a few points where the stand touches the hull has dented the lacquer. In colder weather it can take a long time for paint to harden.

Thanks Gents. It would appear from the link that I am over spraying and not giving enough time too dry. A lesson learnt for the future.
