Tony, i would deffo higher a compressor and gun etc, do a bit of practicing on an old bonnet or something then go for it.

I don't think peeps were trying to knock you about driving it around, but would deffo try and put it back to standard until everything is ready to be put and and sprayed up. Thay way people suddenly see you in a shit hot motor and not something that they have seen build up over time and know what it was.

You put back in for that test?? Maker sure you do and don't be tempted to drive that motor without a license, seen lots of peeps do it and get caught and wait far longer to get back on the road - Ban - fines - insurance etc etc.
