A few liberally brushed on coatings of Zinc-rich and black MIO will cure like concrete and should take all the knocks I can throw at it.
If a job's worth doing it's worth overdoing I always say
Micaceous Iron Oxide paint pretty much rocks!
I thought it would be prudent to strip & prime the underside of the footwell area while access was good
This area will be sprayed with silver/grey MIO when the rest of the interior gets done, just a coat of cold-galv spray for now
Next time out it'll be on its feet again.
