I have some paint damages on the black space frame (buzz year 2010).
I tried to repair some spots with Lacquer Black aerosol.
Only the the existing paint dissolves where the new paint covers the original paint. The old paint is getting soft and can be removed very easily.

What kind of paint do I have to use to avoid the dissolves ?

One of the most important issues when painting aluminium is the primer paint you use. Aluminium requires an acid etched primer. I have used U-POL Acid#8 etch primer to good effect. A suitable top coat can then be applied.

With regard to the dissolving of the original paint I am at a lost and sounds like paint incompatibility. If you leave the paint does it go off and harden.

Is you Buzz 1201?

Hope this helps.

I don't remember very well if it harden. I got some blisters (bubbles) in the old paint. I removed the old soft paint mostly.
Soon I will try again but first will use the primer.

My buzz is 1701.

Hi John,

That will be the Wet & Windy Buzz that was built by Rondar with a centreboard? I don't really know why the boat/ sail number 1701 was given to it, the 2 Buzzes built after it are 1201 and 1202 I think.

On to the main subject, space frames. They should be powder coated when new, but there are different grades of powder coating and i'm not sure what type was used on yours. I always use marine grade, which is the top level and also the most expensive, although still not too bad. I would expect a spaceframe to cost less than 100 to get done, which includes sand blasting the old coating off.

I will be getting some rudder components powder coated soon, I was going to offer getting yours done at the same time, however i've just seen that you are in the Netherlands so probably not possible.

On my current space frame i sanded the old coating down so that the corrosion was removed and the remaining coating was ok, then I used car paint, primer then top coat, to finish. This has worked well to date and has remained in place for about 18 months on salt water.

No, my buzz was build by Cory Yachts.

When I get the buzz at home for the winter, I will try again but now with primer.
Previous time I did not use primer, just black car paint. It was only a 1 2 inches which was damaged on both sides.

When I have problems again I can always look into powder coating locally in the Netherlands.
