Default How hard to remove bottom paint

How hard is it to remove bottom paint? I am looking at a 22 foot bay boat that has bottom paint on it. I am going to trailer the boat and do like the looks of the bottom paint. How dificult to restore to original gelcoat shine? Is this something I can do my self or do I need a yard to do the work? If gelcoat cant be restored what kind of paint can I use that has a shiny smooth finish and will hold up on bottom to the boot stripe.

We have removed bottom paint and sprayed the bottom with Awlgrip, it will hold up well, but you can't leave it in the water for weeks at a time.

The longest that I leave in the water is maybe 4 days. How much awlgrip does it take to cover the bottom of a 22 ft bayboat? Can Awl grip be brushed or rolled Or is it strictly a spray job.

It is likely that you can remove the bottom paint and restore the gelcoat. It has been discussed a lot here, so try the search function for "bottom paint" and see if you can get the information you need.

The process is messy, but worth it.

awlgrip on the bottom may cause an issue if later on you/or the next owner want to keep the boat in the water

Removing bottom paint is the worst of jobs in the best case scenarios. I know, as I have done serveral boats. If at all practical, my first recommendation is to try and retain the original gel-coat by chemically removing the bottom paint. How practical this is depends on how well the bottom paint was originally applied and whether there is a barrier coat ( the better it was applied, the more difficult to remove). Try to find out whether there is a barrier coat and how thoroughly the bottom was sanded before applying the bottom paint. You don't want to pain stakingly remove bottom paint to find sand thrus on the original gel-coat. Also, chemical strippers will not remove epoxy barrier coat, so obviously in some cases having it Soda blasted and refinished is a more practical alternative. This is not a project for the easily deterred.

One of the best pieces of advice about this subject I heard was on another board, simply stated, open checkbook, write out amount, sign and be done with it! I have learned the hard way that sometimes saving a few $ up front doesn't make up for the agrivation during the process and what seemed like a good idea early on suddenly isn't. You might also want to look for a boat that doesn't have bottom paint, you'll pay more but it'll be worth it in the end. Another things I've seen was someone who was able to get really close to matching their original gelcoat with bottom paint. From a distance, you couldn't really tell. I guess it's all about how important it is to you.

Good luck!

It looks like the bottom paint is not a very good job. It is flaking off and the gel coat is underneath. I am trying to gauge the value of the boat. I am looking at another almost identical boat that is one year newer and in great shape. The boat with the bottom paint is in very good shape too, but asking is only 1k cheaper. The owner is ready to negotiate on the boat that has bottom paint. The owner of the boat that does not have bottom paint is sticking to his price. The motors are the same with close to same hours. Just trying to figure how much $ to restore to original. Thanks for the info

If the paint is coming off you have a chance... if it was properly applied in the first place (saning + barrier coat) don't bother, just repaint it...

Thanks guys. I will make up my mind this week. I will probably try to get the boat with no bottom paint. It is a year newer and has a brand new aluminum trailer under it and also more bells and whistles, definatly worth the bit higher price tag.
