There you go.

I think the paint has reacted to some tiny particles of metal dust that the wipe down with acetone has missed, as they have become trapped in the tiny crevices where the weld pool has been , just a thought

Chassis is looking great Andy

Tho maybe its the angle of the photo but the drivers side of the roll bar "looks" higher than the passenger side ? probably the angle of the photo .

cheers

Best stuff to use if not having it powder coated is actually chassis paint and designed for said application. It stays rubberyish so will absorb a knock or 3. Anything else will and does just chip.

What the opinion on hammerite as a chassis paint?

i used hammerite, but i found it chips real easy and its a pig if the temperature isnt right so i coated the chassis in zinc paint first then hammerited. To be honest i wish id sprayed rather than brush painted but its done now and the only chassis rails which will be on display are the cockpit ones which im going to spray orange.

i spent nearly a day sanding my chassis with 300grit paper before i painted it, sprayed it with epoxy mastic 121. in the year its been on the road i have been out in the rain slat grit etc etc so far no rust just a dirty car

the key is in the key. nice scratched metal surface helps the paint stick.

It is Andy...but what a pig of a thing to measure ...its only tacked in place at the moment for that very reason

Chuck roll bar on the floor and get a straight edge that spans the roll bar...measure from this to the underside of the tube to not only get both legs the same but you get the cut angle at same time........simples
