Washing vehicles getting them ready for a full buff/polish job. Using different stages of pads and compounds. I also I would ceramic coat vehicles. I would also vinyl wrap full cars or trim pieces, that the customer is wanting done to their vehicle. I have some window tint experience to.
When cylinder heads come in, checking out the work order, of what their wanting done. To just a surface and a wash to a full rebuild. I would prep the heads cleaning all the carbon build up, with wire brush to walnut blasting them. Installing new valve guides or bore out guide and install a thin-wall in the guide and putting back into spec. I would also face valves, and cut the seats or bore out seats and install new ones. Always using the right angle cutter and always paying attention to detail of specification they should be at.
