Oil primer before woodfiller / bondo?!?

skiposwald

I have been stripping the paint off the wood exterior of my house, filling the nail holes, chips and cracks with bondo and then oil priming it for a couple of years now, and I am happy with the results after several winters. I am thinking about hiring a painter to finish the rest of the house, and he mentioned that he oil primes BEFORE he uses bondo. Is that a bad idea?

Priming before a wood filler can provide a base for the material to adhere to I guess. The abatron wood restoration system for badly damaged wood has a liquid that is applied before the putty-like epoxy.

Bondo would not be my choice for a wood filler but if it is working for you keep going with it I guess. I guess I think of autobody bondo and I think I heard they do have a wood fill product which might be alright.

You still should prime over repairs and patches by the way.

I don't know why I didn't think of this before. I just called the 1800 number for whoever makes Bondo, and the person told me that it should definitely be applied before primer.

that would be correct for anything, bondo? not sure as I have never used it for that purpose, the painter should know what he , she is doing

You know. If I captured the posts of a certain poster I would have a great "How Not to Paint" book for my little publishing empire to publish. If I illustrated the suggestions they would almost be humorous at times.
