Cheers for the feedback guys

Just to let you all know I'm still doing a bit..

The rest of the underside bare metal was given two coats of por15.
Then the areas that were too big for seam sealant were filled out with fisher f1. It's stuff we use at work for attaching threaded bar into stone. it goes pretty hard.



Now I'm just going round the whole underside with brush on and squeeze in seam sealant.



I've done all the arches so far, but there not exactly what you'd call exciting things to photograph.

When thats all done in the next few days, the underside will be getting a coat of primer and then two or three coats of hammerite.
