Spraying enamel paint

[GJM]

Hi guys,

Slightly off topic but couldn't think of anywhere to ask other than here.

We have a Massey Ferguson 135. A wing or sorry, 'fender' fell off prompting the purchase of new fenders.

We have a load of PaintMaster Professional Tractor Enamel and same branded primer and white spirit which I plan to use to spray the panels.

Can anyone give me the basics of how, what mix to use etc.

We recently 'restored' (a loose term) an agricultural grain trailer, welding and finally spraying in said paint.
Thinned with white spirits until not quite as thin a water. Seemed to spray on quite nicely and evenly with no runs.

But there was very, very limited prep work, simply apply 2 coats primer, dry, then 3 coats enamel. So it looks rubbish, but then was never meant to look presentable.

It seemed to take forever to harden, tacky to the touch a fortnight later.

Do i need to use a hardener? If so what type, and what ratio enamel, thinner and hardener?

Finally whats the process for a good finish?

Obviously prep and getting primer nice and smooth. Then what? I've head 3 coats of enamel 1 hour apart. Leave 48 hours then wet and dry 1500 sandpaper to polish?

Thanks guys, basically, how to you spray enamel? ;D

I'm using Turners Trade Paints enamel on my car with a roller, I usually wait a whole 24 hours between coats when using white spirit to thin.

I have used 2k thinner woth enamel, it doesnt 'flow' for nearly as long as the thinners evaporate quicker, so its good for building up coats, I did this on my roof when I was painting it outside to minimise bugs and dust etc getting in while its wet

Make sure you mix the paint thougherly and just add 10% thinners there is proper thinners out there but I must admit I allways use white spirit and it usually takes 24hrs to harden depending on the make of paint used

ok, so you guys reckon there is no need for hardeners?

What about stages, is 3 coats approx an hour appart then wet and dry when its hardened a good route to take?

NOPE 1 coat very thinnly then a full coat There is no need to wet dry it afterwards as all this will achieve is to dull the paint and as it is an enamel you simpy can not polish it up again
