Brief Description:  Cleaning, preping and priming

Well it takes a long time by yourself to clean, Boegel (Desogel) the parts and then prime. Basically it took me all day to complete the Acetone cleaning and Acid washing of the parts. The following day I sprayed the parts with EAP-12 (PPG Boegel) and completed the priming with the CA-7502 Epoxy primer. Dad came over on the day I was priming, however not much for him to do then. Bit boring for him.

It may take a while to complete this process, however, I am happy with the outcome. This stuff is going nowhere and in calculating how much weight I will be adding to the airframe (i.e. read empenage) it should only amount to something in the order of 3-4 kg. That will be max as I just can't get the calcs right and am wasting quite a lot of paint.

I also made a plan detour here. Instead of masking the areas for the foam blocks in the trim tabs, I just sprayed the primer. Thinking this was an issue, I called my trusty paint expert, Ian Irvine. His thoughts were that given the foam can 'hold' water thus increasing possibility of corrosion at that location, his preference would be to spray the primer then scuff that and add the blocks. Interesting....

So I guess I now have an official test being conducted. Elevators have scuffed bare metal then foam blocks, and trim tabs have scuffed primer then foam blocks. It will be interesting to observe the outcome.
