I've read posts over the years extholing P.O.R. as a rust preventative
measure, however it seems there is a 'not quite right' feeling in the
posts about using this product. Is it because the painted surface
'feels' differently than standard primer? Is it easier to damage while
sanding for the final paint coats?
I'm curious because my '53 3600 has rust coming out all over the body.
The rust is coming from underneath. I've tried a few things over the
past 5 years working on a small section on the top of the cab to see
what might work, but even right angle wire brushing down to bare metal
then priming within 5 min, priming again and painting doesn't seem to
work completely. I did this test last about 2 years ago and areas of
the redone cab are starting to bleed rust through the paint again.
I don't wish to go to something like P.O.R. if it produces a soft
texture as I will need to sand when prepping for the 'final' paint coat.
Might there be a chemical I could wipe the bare metal with just prior to
applying the primer? Years and years ago I was an auto adjuster for a
few years and we occasionally had paint overspray claims. I recall one
of the overspray companies putting on a fine display wherein they would
use an oily compound then razor blade the paint off the car. The owner
of this company discussed what works and what doesn't with us and said
in his opinion the best thing one could do to retard rust was to take a
half cup of kerosene, place it in a couple gallons of water and flood
the cars from the top down with it. I never found out if he was crazy
or just wise, but the image stays with me to this day.
Any thoughts?
Many Thanks
