I've just got my fan housing back from the sand blasters and it looks like this... Much better than the last time we saw it My questions are to those guys who've painted theirs... a) did you use / do you need to use high temp engine paints? b) what prep did you do to the actual casting? They're not the smoothest of surfaces in the world to start with! Cheers, Andy.
Did the same as you Andy, but I had my tin and fan housing poder coated. It is a more robust finish than paint, although not quite as edgy. If you get them coated, just remember it is quite thick. We sprayed the fan cage to make sure we had the clearance in the housing. If you paint I would go with a high temp. Ian
mine was done yesterday http://thelatebay.com/index.php?topic=202.20 std paint and lacquer but done by a car sprayer no need for vht on the fan housing
Powdercoat all the way, there are as many colours as there are paints so you can jazz things up with flake pearl etc. Add in the f.act that its robust, hard to scratch and baked on there its hard to beat. Easy to clean too, won't discolour and oils and grease just wipe off. If you look at any of the rebuilt engines that have been painted it flakes off in a couple of years. Aluminium is notoriously hard to paint on, add oils and heat and the future for a paint finish is not too promising. I'm currently paying 40 for a fan casing on its own, degreased, blasted and coated. I have a super special in right now for my 'race' engine, which is £120 for the whole lot, but it's pretty special
i 2packed my tinware in that panelvan transporter blue. With ally u need to prime 1st with a etch primer, then go over with a high build 2pack primer, flat down then spray with a 2pack soild, which means u dont have to laq it have a shine. Or u can 2pack laq over the colour to get a deep shine. Dont forget to mask any faces & bolt holes. >
I would powder coat,if the right colour is not available take the nibs off with a scotch pad and spray it,as the others said it gives a good relatively heat proof base for any topcoat colour you wish to use.People question why spend the money on powder coat to paint over it but the finish is better and will not rust/corrode from behind.
