Painting duragal over penetrol is it ok?

[creat]

Hi,

Im just in the process of rebuilding my trailer and was planning on using penetrol then putting duragal on top. Are the coatings compatible?

cheers

Duragal is aluminium rich - is your trailer already galvanised?
Flood do an aluminium rich penetrol which answers both your questions and cuts out a step as well.

I have used Penetrol before and had very poor results.
The rust came through in a very short time.
I believe that I did proper preparation, cleaning, grinding off loose scale etc.
I would not use Penetrol again.
I have had better results with the rust converter products.
