Right, I've experience machine polishing (spears and jackson rotary polisher) and got some great results on my Celica.
Never tackled the roof - just stuck to the bonnet, boot and sides.
Now I'm going to be tackling the GTi as the sun was out today and it needs some correction...nothing major just some light swirls....
With the roof, how should this be tackled...obviously the same as the bonnet, small squares taoped off and done slowly as per usual though it;s the height.....step ladders??
