Well fellow
campers I have just completed the coating process of the chassis and I
must say I am wrapped.
I intended to use
keycoat primer first and then a product called Herculiner as the robust
final skin. Well the best laid plans of mice and men went belly up as
the rather expensive Herculiner product was when opened found to be
completely shot...that is it was partly set and unusable.
So it was to plan
'B' and I decided to use a K&H product called C. Guard as the final
finish and I loved the stippled result. Remember I started with Duragal
as the material used to construct the chassis (which has an inline
galvanised finished) and I lightly dulled the surface with very fine 3M
Scourer.
I then cleaned
the sanded surface with a grease and wax remover, allowing to dry and
applied the keycoat primer by spray gun. It was at this point the
trailer received the C. Guard and the photos show the end result.

trailer looked like before any preparation for coating.

the suspension.

the applied coating still to dry.

Pic No.6 Close up of the
coating at the pointy end of the trailer frame and I think you should be
able to see the stipple effect I was trying to describe.
