gruntus Posted August 16, 2008 Share Posted August 16, 2008 Gents, A while back Les displayed his immaculate 300TDi engine with nicely refurbed and painted timingcase etc. He used Comma 5 wheel silver for the alloy which didnt need any primer however I seem to be only able to get Simoniz Alloy 5 wheel silver. I dont see any reason to not use the Simoniz stuff but there is no mention of applying direct without primer and its also Acrylic (which I have no knowledge of and unable to get details of Comma stuff to compare). So my question is do I need to primer the alloy first and is Acrylic ok for the intended use? Dumb question I know but worth asking before it starts peeling off in the engine bay in afew years time... Didn't want to PM Les direct to ask as he may think I am stalking him.... If I have no definate answers I will just play safe and primer anyway.... Thanks G Quote Link to comment Share on other sites More sharing options...
Les Henson Posted August 16, 2008 Share Posted August 16, 2008 I think acrylic paint is for plastics? I wouldn't use it unless it stated for definite that it would be ok to use on hot metal surfaces - same for the primer. You could use Sperex (VHT) paint, but the colour range is a bit limited, and it really needs to be baked on (can you get a whole engine in your oven, and would wifey kill you if you tried it? ) Specific wheel paint is designed to take the temperature from the brakes, so is ideal for an engine too. There is also engine laquer, which I used on the block and sump, but if you don't want to brush it on, you will need spray gear. The colour range is also limited. I would imagine that any 'wheel paint' would be fine. It's possible that any 'alluminium paint' will also be suitable, but the only way to be sure would be to do a test piece and then put it in a warm oven. The paint might tarnish over time though, and become brown. Les. Quote Link to comment Share on other sites More sharing options...
steve_d Posted August 16, 2008 Share Posted August 16, 2008 If you go to http://www.commaoil.com/ Hit where to buy then put in your post code it comes up with loads of places Comma products are sold. Steve Quote Link to comment Share on other sites More sharing options...
gruntus Posted August 17, 2008 Author Share Posted August 17, 2008 Hi Les, Thanks for the reply. The Simoniz 5 Wheel Alloy spray paint is for alloy wheels (I was initially sceptical as I remember Simoniz best from its "Back to Black" and cleaning products) and my nearest local motor factor and halfrauds stock it. I think I will wait and go with Comma as theres no point reinventing the wheel (The Mrs would probably notice if the inside of the oven turns into a spray booth ). By the way how many tins did you get through Les? With regard to the block I have already painted it with Red Tetrosyl Engine Lacquer by brush and the results are nice. For preperation I used a wire brush in a drill (the type that looks like an old brush from a coal fire rather than the usual round type) and used Carb Cleaner to chase of the debris and degrease. Hi Steve, Thanks for the link I had tried this yesterday but the closest ditributor is Dingbro who are trade only and the next local stockist isn't quite close enough to pop around to. I will give them a call to order the stuff in and collect next weekend. Thanks for your help gents. Cheers Grant Quote Link to comment Share on other sites More sharing options...
Les Henson Posted August 17, 2008 Share Posted August 17, 2008 I used 3 x 400ml cans. This gives you enough paint to put several coats on each component Les. Quote Link to comment Share on other sites More sharing options...
