should I use compound
« on: October 09, 2010, 07:20:00 PM »

Chaps

I've just finished my final gloss coat on my hull, (I have used Halfords spray cans) and I want to get a high gloss finish. Should I use compound, then polish or should I use 1200 wet & dry first, then conpound and polish?  {:-{

Cheers

Have you lacquered it or just a high gloss paint?

 Hi Nick

 I used a compound called Farecla G3 , got a mirror finish  :-)) . If you havent any paint runs or imperfections then you shouldent need wet & dry but use plenty of

 water.

Hi Nick
I'd use compound first & see if that gives you a good enough finish. Wet & dry scratches are as easy to get out as you might imagine, so i would only try it if compound doesn't do it well enough. wet & dry is available down to 4000 grit from specialist suppliers, 1200 grit can be awkward to polish out, although I believe its the finest grit available from halfords. If you use 1200, rub the paper on itself a little before using it to remove some of the sharpness. this will help calm the scratches down, also use plenty of water & a little washing up liquid.
G3 is good stuff used with plenty of water as stoney suggests, try to rub at 90 degrees to the direction you flat in to start with & finish with circular motion, & above all be gentle with the flatting & be patient !!! Better to take a few days polishing than have to repaint it.

Hi again

I took all your advice and used some G3 compound this afternoon, and it did the trick  :-)) I got a fantastic mirror finish. I haven't finished compounding it all yet but the area I have done, looks FANTASTIC, cheers guys, thanks for all your help. Would I be right in saying, after I have finished compounding the hull I should polish it, or is there anything else I should do to get that glass look finish?
I haven't used lacquer before but am I right in saying, if I get a high gloss finish from compounding and polishing, then I no need to use lacquer?

Thanks again
Nick

 Hi Nick

 I personally would'nt use lacquer because if you get any scratches or chips on the paint it will be harder to repair just use a good quality polish.Halfords do touch up paint pens if the worst happens.

Hi Nick, glad it worked OK for you. if you really want the ultimate finish you should use a finer grade compound after the G3, theres g10 or 3m finesse it. both excellent products. to be honest there aren't really necessary. Yes you should polish it after compounding to achieve the best result.
Lacquer isn't required if your happy with the finish. some say lacquer will give you a more resilient finish, but I'm not convinced of this. Maybe if you used 2 pack lacquer it would, but you need professional equipment to get the best results using 2 pack. spray can lacquer will have about the same hardness as the spray paint you used already, so I don't see the point if you are happy with the result you already have.
If you do decide to lacquer it, flat it down with 1200 grit wet & dry used with plenty of water & a little washing up liquid. wash it off, then dry it throughly. then clean with pre paint, spirit wipe or something similar to remove any traces of grease etc. white spirit will do the job OK if pre paint isn't available, but sometimes it can melt the paint slightly so use caution & only do small ares at a time & most important of all KEEP YOUR GREESEY FINGERS OFF IT !!!
But first of all see what it looks like after a G3 & a polish. Good luck
