LR90 Posted December 2, 2006 Share Posted December 2, 2006 Well, its slowly comming together. I've had a new wide saddle TD5 bulkhead blasted and now galved. No sign of distortion though the surface is much rougher than the satin black paint from new and the vent grills are heavily clogged. So, reassurance for others seeking to galv a bulkhead. In fact it seems the biggest risk comes from handling, the bulkhead which looks very fragile amongst the other items in for blasting or galving in the yards I've been using. That said mine has come back fine and I now need to tidy it up a bit and get some (yellow) paint on it. So, what's the recommendations for painting onto galv?

Guest diesel_jim Posted December 2, 2006 Share Posted December 2, 2006 Well, its slowly comming together.

I'd get the bukhead shotblasted back to bare steel, that way the paint will stick well...... (slam of door, screeching of tyres in the distance..... ) I think etch primer is the way to go, although how good it is, i don't know. I've also discovered that leaving galv outside in the rain and weather helps to dull it (my chassis and rock sliders certainly have dulled a lot) and it seems to help the paint stick a bit, albiet only hammer****e, but nevertheless it helps it a little.

muddy Posted December 2, 2006 Share Posted December 2, 2006 I use a primer called MARSFLUID which you paint on, leave for 10 mins until it goes black and rthen just prime and paint as normall, seems to have worked well on my galv rear x member.

freeagent Posted December 2, 2006 Share Posted December 2, 2006 it will stick better if the galv has had a chance to wheather slightly.... leave it out in the rain for a bit. Quote Link to comment Share on other sites More sharing options...
LR90 Posted December 2, 2006 Author Share Posted December 2, 2006 I am begining to wonder about just leaving it unpainted? Less effort, which I like, and the truck isn't a show piece anymore. Brush paint I could do but spraying would be using cans and even then I don't have a lot of space. Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted December 2, 2006 Share Posted December 2, 2006 Leave it bare Trev, it looks much nicer Mo Quote Link to comment Share on other sites More sharing options...
gruntus Posted December 2, 2006 Share Posted December 2, 2006 Hi Trev, Bought the same item with the intention of Galving but the galv shop insist all paint must be removed before they will dip it. That woud be fine if the new bulkhead was sprayed instead of dipped in paint as I have no way of getting the paint off from the internal sections of the bulkhead. I have tried nitromors and cellulose to tryand lift the paint but the stuff is refusing to come off. I am now thinking about just painting it and then giving it a liberal dose of dinitrol inside and out. Cheers Grant Quote Link to comment Share on other sites More sharing options...
LR90 Posted December 2, 2006 Author Share Posted December 2, 2006 I had to take mine to a blasters first coz they wouldn't dip it as it was and yep, it even removed the paint inside. Left the surfaces very rough and while they were concerned it might blast away the vent grills they were still intact (if a little buckled) after. Did wonder about getting it hot zinc sprayed at the same time but glad now I've done it to go the whole hog and get the hot dip galv. Lot of chasing about so far though.

western Posted December 2, 2006 Share Posted December 2, 2006 IIRC the underscreen vent grilles are rivtted on, you could have removed them before getting it blasted/galvanised Quote Link to comment Share on other sites More sharing options...
LR90 Posted December 2, 2006 Author Share Posted December 2, 2006 They are on my older bulkhead but these where spot welded on. Though you've made me think I could perhaps move my old ones onto the new b/head. Quote Link to comment Share on other sites More sharing options...
Tonk Posted December 4, 2006 Share Posted December 4, 2006 Trev, AFAIK there is some stuff called T wash that u brush onto galved surfaces to bite in before painting, phone a commercial painters, Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted December 4, 2006 Share Posted December 4, 2006 Acid etch should do it, there's also hammerite "special metals primer" which is about the only hammerite product that seems to work nicely Quote Link to comment Share on other sites More sharing options...
