ok so i can now infuse succesfully but have been doing so without a gelcoat or duratec,instead i have been spraying a rattle can laquer and polishing this,im not happy with the finish im getting on the aerosol and feel i would be better to make the effort to change to spraying duratec into the mold and avoiding the laquer stage altogether,just buffing the duratec.
problem is i have no air equipment,and i have to use it indoors.i only make small parts,largest is 2 foot by 8" so i would hope to use a small gun.so what do i need? a compressor,some sort of gun and the correct duratec?and recomendations would be helpful,either from ebay.co.uk,machinemart.co.uk or cromwelltools.co.uk or similar.any help very gratefully recieved!if i could get equipped for £200-300 that would be ideal.
Here you go then all from ebay. Ive just done a quick scan so a little more time and im sure you might find cheaper. The compressor with a 50 litre tank should do you (mines 200 but ive got it in the garage, dont worry about the noise because for the parts you are spraying just charge the tank and switch it off. The gun is HVLP, less overspray and less pressure required, just make sure the free air displacement of the comp is the same or greater than the gun. this gun has a 1.4mm tip which is ok for what your doing. The regulator to regulate the supply to the gun + filter/water drain, youll need fittings and hose (all off ebay)The duratec from Polyfibre (i think youve used these before, it is sold as Durabuild but it is Duratec)Dont forget a mask, 3M do one for a tenner,search on ebay they are there.
There you are then it`s a start.
cheers m8 
might even be able to run a small air polisher with that compressor.
