chassis paint

[jayzcycles]

hi,please could someone tell me wich paint to use on the chassis.i have some flaking paint do i touch up with white hammerite or use underseal.thanks.jay.

Hammerite is often used but is 'orrible (and sometimes brittle).Frosts POR 15 has its fans but seems only to like keying to bare or rusty metal although once applied properly seems to stay put. I've recently used a Ronseal product called 'No Rust'that gives a decent finish off brush and seems durable so far although it's not been exposed to winter crud yet (the maker's claims are similar to Hammerite but it goes on easier). Have heard of some marine products being used too but have no experience of them. Try searching, it's a perennial issue....

i can highly recommend POR15 although my chassis was only slightly scabby on the corner plates, it seems to have bonded well to the clean bits as well,but i spent a long time prepping(lets not go down that road)followed by several sprays of waxoil.it really does help if you can use a ramp,i pressure washed all the nooks & crannys really does pay to do a proper job.good luck with the painting.

POR15 on my Audi has rust coming through it after 6 months. AFAIK it has no 'rust killing' properties - just seeks to seal the rust from the air, prcluding further oxidation. Other's experiences differ greatly though...
I've done my chassis with zinc primer (which does have alleged rust 'killing' properties, covered over with hammerite on the wishbones and stone guard on the chassis. 30 months later it's all still in tact. Use waxoyl or similar on the surface rust in areas a brush won't reach. Believe me you don't want to be doing this job twice, so do it right!

Grifter ill go with using a metal treatment first as you say.problem is i will take the pepsi challenge with any so called rust killer none of them work long term and over the years ive used most, once corrosion as started all you can do is slow the process down.

Agreed - I try not to drive mine in the rain so as not to speed the process up again!

I started the joyous task of prepping mine yesterday.
So far I've removed most of the loose paint, smoothed down with wire brush and wool and then given a good coat of rust killer.
I was then planning on applying a few coats of hammerite before covering with waxoil.

I'll let you know how it goes.

hogbenc if you havent already i would strongly advise hosing out the gusset corner plates on the tube ends .A,so you can dilute any salt thats still lying there.B,hose out and have a good poke around to get all the stones & dirt out of the plate top sides,pay special attention to the outriggers.Grifter i agree the less it gets wet the better,i dont use mine when the roads are salted & gritted.That salt is a BAST*RD.good luck with that chassis job Hogbenc.

while on the topic of the chasis when all the bolts holding the floor pans and seatbelt parts is removed is it possible to lift the body a little to gain access to the outrigger side rails, as mine has aloads of rust basically they have been stone chipped and the water has gone under the powder coat most is just surface with a little pitting. Sanded all down now need ideas on how to paint up in the gap between body on top of the side rails, would be easy if I could lift the body a little.

There are quite a few bolts, 28 if I remember correctly (4 behind the fuel tank for example), then you'll have to remove the brake/clutch lines from the master cylinders. The gearlinkage will have to come off also. And a load of other things.

Many people say that they are thinking about lifting the chassis a little, but in reality it's a much bigger job than they realise! Not saying don't do it, just go in to it with your eyes open.
