hard work and elbow grease, removing all the sound deadening material, then painting the inside.
Chris had hand painted the roll cage with Hammerite.
Lots of work sanding the brush marks out, the only part of the car that has seen a rattle can - the cage!
Trying to paint over rattlecan or hammerite with proper automotive paint requires a barrier to stop reaction.
In this case, it was easier to stick with rattle can type paint, this project is a shoestring budget and I didn't want to spend money on the primers required to stop the paint reacting with poly base/2k.
Word of warning here guys - its better not to go down the rattle can route in the first place. The paint is rubbish and often ends in regret (with the exception of proper 2k paint thats been put in a can for those without spray equipment)
