Yet another underseal / rust prevention thread!

[Jags C20LET]

Bear with me chaps!
I noticed the other week that the back end undercarriage was getting a bit scabby.
Today, I removed the rear section of the exhaust and fuel pump.
With the aid of a knotted wire dohicky and a drill-wire wheel combo I got shot of as much rustyness as I could.
I then slapped on a liberal coat (read that as shedloads) of Kurust.
When that had dried, applied seam sealer to where it looked like it needed to be.

Next step......what now?
I was thinking about hammerite primer, followed by white smoothrite, followed by black hammerite underseal, followed by a good coat of black waxoyl.

Not enough, too much?

Opinions please!

Cheers.

Re: Yet another underseal / rust prevention thread!

sounds like overkill to me i just prime then seal from bare metal.


acid etch then stone chip or and waxoil.

but that said the more the better i spose.

I know I sound like a stuck record but there is only one rust paint for me .... and I've tried most over decades

POR-15 .... look it up ...

PS, it works .... it really works ...

Thanks for the tips guys, but I have to have it done tomorrow, so can only really use locally aquirable stuff, ie Hammerite stuff.
I'm going to do my fuel tanks soon, so will get a hold of some POR-15 when I do that.

Why white Smoothrite?

What you are proposing is basically what I did to my entire underside about 5 years ago. I used an enamel rather than Smoothrite though as you can't overpaint Smoothrite or Hammerite with any other paints. It has lasted reasonably well.

Why white? good question. white, because I was going to buy some clear waxoyl, and if it was white paint, my theory is that the rust would show through. however, i found some black waxoyl in my shed, so its doesnt really matter what colour it is now!

I did think that might be the plan, but you said about putting black underseal on which stumped me!
