In a quandry?
Most of the underside has now had two coats of bonda rust followed by two coats of rustoleum combi color and two coats of synthetic radiant red.
A few hard to reach bits had the rusta bond over sprayed with coach enamel which the synthetic red doesn't like.
Since I made an arse of one rear wheel arch and will have to gravitex it, I'm hoping a thinned coat of gravitex over the coach enamelled bits will stop the synthetic reacting with it?

Main question though, is it really worth stonechipping the whole underside when it's already had six coats of paint?
Given it's not going to be used a lot, might it not be better just leave off the stonechip and be able to see any bits that needed touching up or will it be like sitting in drum when stones bounce of it.
Going to be a pita to stone chip it all and the have to give it at least two coats of the synthetic and I'm not even sure the gravitex will take to the paint that's already on.

Nearly all the new brake lines are made so thats one pain of job out of the way.
Need to finish painting the underside, two new front dampers and a pair of adjustable trailing arms and I can start putting it all together. Might get it on the road this summer.
