Cheers for all the great advice, I will be painting them just need to build up the nerve to attack them.
I cant seem to find a step by step guide for painting them, just really worried that I will make them useless by over doing it.
cheers again for all your help guys
I'll see if I can russle up a guide at some point but in the meantime I hope the below helps.
Ah don't worry I was thinking the same thing but its surprisingly easy. Ideally do it on a non windy day, which judging by the last couple of days weather might be a harder than it sounds.
Firstly grab some gloves you don't mind getting paint on. If you bought the sensor that Pree has in his guide, then grab the drill tool that comes supplied.
Get some cardboard, use the drill tool to mark holes in the cardboard. With a bit of pressure you can cut through the cardboard with the drill tool to make an accurate sized hole. Try to make the hole(s) near to the edge of the cardboard, say 3-4cm from the edge. Then take some scissors and cut a straight horizontal line towards the hole you made with the drill tool. This is to feed the sensor towards the hole and allow the cable to fit through.
Push the sensor into the hole, pulling gently at the back for a snug fit. Take your spray can and holding it facing downwards towards the sensor, lightly spray a coat. Then wait 10-15mins
Then spray another coat. Then wait 10-15mins
Then spray the lacquer clear coat.
Repeat for the remaining sensors.
I let the paint harden for a week before I washed the car again.
If you find some paint has found its way into the grooves, don't panic, you can use a pin to go around in a circular motion to remove any excess paint. I have some paint which worked its way into the grooves on mine, but it hasn't affected the ultrasonics in anyway and I didn't bother to remove it as its hardly noticeable.
Any other questions feel free to PM me.
