Hi guys hope some one can help.

 I was advised to use a BASF product which is a self eching primer but I cannot easily obtain this in my area . 

 I have found a Spies Hecker paint that says its a wash primer, chromate free but does not use and activator like the BASF product. 

 Question does anyone have experience of Spies Hecker 4085 primer or know if this is find for our airframe materials??

   

  Supposed to be shipping this week my kit.

 Thanks for any help

Kev

Hi Kev,



You need a self-etch primer for painting aluminum.  If you use an 

ordinary primer on the aluminum you need chemical preparations like 

Alumiprep and Allodine to get rid of the invisible oxide that is 

usually found on the aluminum.



It is a good idea to test your actual paints on some scrap aluminum 

before painting large parts of your plane.  I found the self etch 

primer would stick nicely to the aluminum but would be lifted by most 

top coat paints including rattle can enamel.  This problem was solved 

by using an ordinary primer on top of the self etching primer and 

under the top coat.



Good luck,



Paul
