    Posted: 04 Aug 2012 at 7:17pm
I'm considering VC Performance epoxy paint for my 18' aluminum hull.  I intend to strip the bottom bare and prime with a self etching primer.  I plan to sand the paint on the sides which is in fair condition and has no adhesion problems, and then paint over it.    Will this paint be ok with my plan or does it require special primer and wil it go over the existing paint on the sides.  I understand it need three to four coats and hope to get that done with the 2 gallon package.  I figure with the transom I've got 120 sq ft or so.

VC Performance Epoxy is an epoxy based bottom paint, which contains very aggressive solvents. Due to the fact that it contains such aggressive solvents, it can only be applied overtop of existing two component products which are well adhered and in sound condition, in order to prevent any solvent attacking. Therefore if either the existing coating (on the sides) or self etching primer are two component products which are in fact well adhered/intact then you will be just fine to proceed along with VC Performance Epoxy.

However if either the existing coating (on the sides) or the planned self etching primer are single component products, then it will be best and recommended for you to avoid any applications of VC Performance Epoxy overtop as you could very well end up with some blistering/detachment if attempted. Instead, you should apply 1 coat of InterProtect 2000E which has been thinned 15% by volume directly onto the bare aluminum and prior to applying VC Performance Epoxy.

Thanks for the info Jay.  Your answer poses some additional questions however.  First, how long should I let the InterProtect 2000e cure before applying the VC Performance?  And why not just apply a couple more coats of the 2000e and forget the VC Performance?  Or is there another product more suited to my requirement for a sprayable very hard finish that wll take some beach punishment.  I don't expect miracles from the paint, but I want as much saltwater and sand protection as I can get.  And I take it from your answer that I could spray the 2000e over bare aluminum without priming.  And thanks again for your help.

You are certainly welcome for the information. InterProtect 2000E is in fact a primer that produces a hard and durable finish, which can be applied directly overtop freshly sanded/ground/blasted aluminum with no issues at all. Unfortunately though with this product being just a primer, we generally do not recommend applying this product and the leaving it as is as it has no UV stability therefore fadking/chalking/discoloring would be expected. Therefore the hardest and most durable finish would consist of InterProtect 2000E followed by VC Performance Epoxy and that would remain as my recommendation.
 
When applying VC Performance Epoxy overtop of InterProtect 2000E you generally have a couple hour window to do so, see below:
- 50F: 5 hours minimum to 9 hours maximum
- 73F: 3 hours minimum to 7 hours maximum
- 95F: 1 hour minimum to 5 hours maximum
 
The overcoating time between coats of VC Performance Epoxy are as follows:
- 50F: 6 hours minimum to 24 hours maximum
- 73F: 5 hours minimum to 24 hours maximum
- 95F: 4 hours minimum to 24 hours maximum
If you were to exceed more then 24 hours between any coats, it would be recommended to sand the prior coat with 180 grit paper prior to recoating for ensurance of adhesion.
 
Hope this helps!

Thanks again Jay.  Solves my problems even though it'll add another 200 bucks to my paint job, but I think it's going to worth it in the long run.
