It wasn't that rough before those photo's, that was the result of the Gunk, a severe jet wash and rubbing down with wet 'n' dry, i'd never be that messy or disrespectful to my bikes!!
After that bit of prepping the first spray started to bubble because of reacting to the engine brightener which i presume has some sort of silicone in it.
It took several attempts of thinners then sanding before the spray actually took properly, the main problem area being on the top of the fins.
If anyone's considering doing this, make sure you thoroughly degrease the engine with Gunk and a brush, otherwise you will have no end of a headache. Fortunately my mate knows what he's doing, hence the results.
I used a Plastikote Satin Black spray, but didn't use lacquer as i didn't want a glossy finish.
I was reassured it would be fine on the engine as my mate has used it on his car engine with no problems whatsoever, and it was done in the old fashioned way with the engine still on the bike as the photo's show.
Oh, and i must put a word in for the weathermen who said there was a 10% chance of rain on Sunday.
What they didn't mention was that the 10% would be all over my house for most of the day
