Yes Paul and Rebecca. Welcome to the scabby aka club. I thought I had got out of it pretty good after 2 1/2 years without a paint bluster but then one day I opened up the aka bag and 2 of the akas
were blistered to buggery. After rubbing back thoroughly, I used Glyptal as a base before spray painting
with a high temperature engine enamel but it's early days and although, so far it's standing up pretty well, I can't be convinced yet that it's the best coating. Others may like to comment on their successes or failures. http://www.glyptal.com/1201tech001.pdf
Best of luck with it.
Don't take life too seriously................it ain't permanent.
