Harrison L5 rescue

Hi Andrew, I know what you mean and it is a problem but this paint is the lesser of the evils like cellulose its tens to dry in the air so londs as dust as long as things are not too close to where the item getting sprayed is. The enamel type paints like the old Techaoyd type stuff is horrible the whole workshop takes a coat of fine wet mist, two pack is not much better too.
I like this paint for finish and hard wearing but the less mess element of it is the main reason I like it.
Cheers Mick.

Cracking job Mick, I certainly admire your tenacity. Nice big open work space you have there too - I'm very jealous of that!

Hi there, Mick,
I certainly agree with both of Pete's comments.
Nobody has responded to my requests for help about painting on my Myford QC Gearbox thread. Once I've drilled and tapped all the holes for the fittings on my gear cover casting, I've got to paint it. I was anticipating using Hammerite Special Metal primer, it's water-based and I assume from the chromate yellow colour it's an etch primer. Then I was going to finish coat with Myford grey brushing enamel. Alternatively, I might use what John Stevenson calls a 'rattle can' if I can source one the right colour at an affordable price. That would be the nearest I could get to spray painting. I hadn't considered using a filler - what filler have you used?
I've recently been watching a series of Youtube videos by Dan Gelbart. His video on surface preparation is interesting. He reckons preparation by washing with a solvent is useless because it leaves a surface layer of hydrocarbons one or two molecules thick, microscopically thin but he says it's still thick enough to prevent the paint bonding to the metal surface. But then he's using powder coating.
He also shows a natty electrostatic painting rig - the job is grounded and the paint (powder) gun is at 30 kV!!! :zap: :zap: :zap:
I don't remember his giving a maker's name for the gun and I haven't researched it myself yet.

Cheers Pete ,
Hi Pete W I havent seen the hammerite special metal primer but if its water based I doubt it will be etch primer but I could be wrong. You can get rattle (spray cans of etch primer from motor paint suppliers ) which might be an option , you can also get spray filler primer too in cans but to be honest its not as thick as you could spray it through a spray gun so a half hearted version really. Rustoleim brand do good cans of gloss in lots of machine and RAL colours , they probably do primers too, Cromwell tools sells them so you could look up online.
In general with this old stuff if its not too big or a total nightmare shape you are better off getting back to metal or mostly metal, then using car body filler Davids isopon P38 or similar fill the worst deep stuff or if an area has multiple srtatchs , gouges or dents try to do a skim right over the area and then sand down using say P80 grit with foam block etc to contour it, once the shape is ok and edges feathered in sand overall with say P240 then 320 then etch and then filler prime it, you will then see how good you have got the surface and may have to re do some areas but the bodge is hard and sandable in minutes and the primers both dry quite quickly too especially if you warm the part with a fan heater too. Once you are happy with the primer give it a light sand with about P600-800 and three coats of gloss if you are spraying and you should get a good finish.
Its all in the preperation Pete so unless your finshed primer once sanded looks spot on your top coat will only highlight any flaws, Mind I am being a total fanny here and want car type finish so you can probably cut some corners and still get a smart looking finish for a machine :)
Bob ...............You aare dead right Its about time I got this project done :palm:... next week will see big changes, today a funeral and dentist appointment spoilt progress.
