Problem with primer on chassis
Has anybody seen this before ? Have been having a wee test with my metal primer..Dulux Metalshield in grey ...i painted a bit over the front frame last night and when i went out this morning there was brownish blotches that looked as if it has come through the primer...especially bad around the welds...now i did give the rails a good polish with flappy disk and a final wipe down with acetone so i thought it would be contaminant free....the paint has been in the garage for the last few months could it be gubbed due to extream cold ?? would be pi$$ed off cause it cost me a few quid and unused

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 andy

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?

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

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.
